RE: Running norcild 1200 off the alternator

I have occasionally run the fridge on inverter while driving at high altitudes. The 425 watt heaters should draw about 45amps at 12 volts. Adding 10 to 15 amps for chassis demands total altrnatorload should be 60+-. The alternator on the cat diesel is supposedly rated to 160amps. No that alternator should handle it just fine. Why did you come to the conclusion the alternator is bad ? Low voltage ? If so, it is either the diodes of the voltage regulator inside of the alternator. If you are handy enough to replace and alternator, you are handy enough to replace the voltage regulator. The rest of the major parts (bearing, slip rings, brushes, windings) in an alternator last a long, LONG.

RE: Portable generators with auto start capability.

Some inverter/charge/auto transfer units, Samlex EVO for example, have a generator starter output built in. From page 74 EvolutionTM Series Inverter/Charger Owners Manual 4.7 AUTO GENERATOR START / STOP Auto Generator Start / Stop function has been provided using “Common” and Normally Open “NO” contacts of Status Relay (14, Fig 2.1). The relay is SPDT Type with contacts rated at 3A, 125 VAC / 30 VDC. Appropriate external Generator Auto Start / Stop Module will be required for using this function.

RE: 6v vs 12v

I have 2 12v deep cycle batteries instead of 2 6v deep cycle batteries. When you plan on replacing them two 6V golf cart batteries will usually store more energy and cost less.

RE: Class B for 3 adults?

depends on the relationship of the 3 adults, but no you need to look a "C"'s Not real common, but a B+ might fill the bill. Basically a C without the overcab bunk. Maybe a bit shorter.

RE: How many amp-hours?

For batteries, I recommend a pair of 6V golf cart batteries. That is about 225 AH @ 12V. These would be cheaper and store more energy than a pair of dual purpose marine/RV batteries. AGM golf cart batteries are available but are $$$ ! The real issue is recharging, especially when shaded or during short days. I think you are going to need more solar panels than you can practically mount on a TC. This means a generator or a DC-DC battery charger (and running the truck engine for hours) is a must ! Don't forget a good battery monitor like a Victron BMV-700 !

RE: Mildew/mold(?) on wood under roof

I would have added some bleach to your favorite cleaner. Overnight is an enclosed building with fans blowing would be the best solution. Watch the walls carefully. The may delaminate.

RE: Class C Battery issues

A bi-directional smart solenoid reduces these problems by a factor of 99% I do NOT disagree, but a DC-DC battery charger instead takes it to 100% !

RE: Hard Core Shopping: Best Laptop Buy For The Buck SSD ?

Sadly, like most big companies, all of the major laptop vendors are cutting corners to keep prices low and make a buck. When it comes to SSDs, there is good, not so good and bad. We are all used to rotating disks lasting years, but the cheapest SSDs might not even last 2 years. Of course it is very difficult to know what you are going to get before you lay your money down. If you are a little bit adventuresome, I recommend the Raspberry Pi 4 Desktop Kit Raspberry Pi 4 Desktop Kit. Under $150. Add a Digital TV and you are in business. Pre-loaded with Chromium browser and common office tools. There Raspberry Pi community is very helpful. There was a minor hardware "bug" but it has been fixed. Also the latest version of the software allows you to boot from a USB stick or SSD connected via USB (adapter - $15 ; Samsung 970 Pro M.2 SSD - $150 .

RE: F-250 Needs New Shoes

All the experts says replace "old" tires. If they don't have serious dry rot and are not leaking air, just keep driving.

RE: Class C Battery issues

Take your engine battery to NAPA have it charged and tested, in that order. Replace you house battery disconnect with a DC-DC battery charger. Not cheap, but it is 100% automatic and you can be sure that it will charge while driving. Also you need to verify that your converter is output sufficient voltage to keep the house battery charged. You should have about 13.4V at the house battery when plugged in. If not, there are a lot things to check. Water heaters are tricky. There are multiple safety features that will prevent it from starting. Each needs to be tested.

RE: Improving Fridge Cooling

Correct me if I'm wrong- I think a 12v fridge comes only in beer cooler sizes. Totally impractical to run an RV fridge on 12V alone.David You are incorrect--though there are small units availble: https://youtu.be/jMCdrE-4jBI Segue - The Danfoss company has been making refrigerant compressors for many years. They don't kame refrigerators or A?C units, but their compressors are used by many companies. Their 12VDC compressors are very interesting. They take 12VDC and run it into a 3 phase inverter. (3 phase motors are much mire efficient than single phase.) The 3 phase AC has variable frequency so that the compressor motor can spin at different RPM as the load requires.

RE: Batteries

Depending on your goals, yes. Cheaper batteries won't last as many years, but they will last as many hours as similarly rated ones. A pair of golf cart batteries will likely cost less than a pair of Group 24, dual purpose Marine/RV batteries and will store more energy.

RE: Mini Winnie needs major work

This is a real "shot in the dark" ! If you have the time, the talent and the energy to stick with a long term project, you could make a fair profit on this. For giggles, contact RV ROOF INSTALL and see if they will give you a ball park quote. New roof, delamination side repair could easily cost >$20K, but it might be worth it !

RE: Improving Fridge Cooling

... at most the unit can probably create about a 40 degree F temp difference, ... I think that number is a bit optimistic, but the bottom line is you won't be getting "ice cold" beer out of one on a 90F day ! 12VDC compressor refrigerators DO EXIST ! However, a good, Energy Star, high efficiency residential refrigerator, an inverter, some decent house batteries (minimum TWO 6V golf cart batteries, 4 is better) so solar panels (or a couple of hours with a generator and battery charger) and you will be a much happier camper.

RE: Battery Life?

Rarely, if ever, do the batteries go below the 50% charge level. Dropping below about 80% SOC on any lead acid battery will shorten its life. Current batteries are Interstate 27DC Marine/RV from Costco. I think at least 2 of my previous sets (which lasted longer) were the Costco branded ones. Costco now sells Interstate brand. A pair of 6V golf cart batteries will store more energy, last longer and likely cost less than a pair of Marine/RV batteries.

RE: Batteries

Duracell golf cart batteries are sold at almost all Sam's Clubs at a very good price. Interstate golf cart batteries are sold at almost all Costcos also at a very good price. No they are not Trojan T105, but they are decent batteries. A pair will hold more energy than the pair of Group 24s you have now (about 225 Ah vs 180 Ah) and will likely cost you less ! I would still take a generator and battery charger, "just in case". Don't count on charging your house batteries from you vehicle unless you have a DC-DC charger.

RE: Residential Fridge versus three-way in a Class B or C

First, I am 100% in favor of compressor refrigerators, be they 120VAC or 12VDC. They just work better, especially in hot weather. So the question, the Class B+ comes with two 12 volt house batteries and a 1000 watt inverter. A pair of Group 27 "dual purpose" batteries will give you about 180 Ah of power. A pair of 6V golf cart batteries will give you about 225 Ah of power, likely will last longer and their replacement will cost less ! A 1000W inverter may or may not adequate for your refrigerator, depending on the model. Some are very efficient, some are not. BUYER BEWARE ! Do your homework ! Sadly, RV manufacturers are SEVERAL years behind the "technology" curve. You would be better off with a with a inverter/charger/automatic transfer switch and just a DC distribution panel, no converter. Sadly, few RV manufacturers offer this. I’ll also get a solar panel and controller on it. I do plan on boondock it quite a bit in the back country in Nevada. Should I have any power issues? If I run the generator a couple of hours a day plus having the solar will that keep the batteries charged? Not enough information ! How much solar ? How big of a generator ? If the generator has to run an A/C then it will take a lot more than "a couple of hours". Also, do no bet on driving to recharge your batteries, unless you get a DC-DC charger.

RE: Buying a new travel trailer-first time buyer

Not sure if this is your first RV (not just first bunkhouse), but I strongly recommend you rent a trailer for a couple of weekends to see if the family really enjoys it.

RE: Confused and Frustrated

Hello all..I am looking to purchase a camper to full time live in. I will be a solo female, not mechanically inclined (but will have to learn). That is "deep water" you are about to jump into ! I strongly suggest a few weekends with a rental. You will then know what it is like to drive one and live in one. IMHO, full timing in any motorhome, regardless of size, is an issue. You can't just "run to the store" for milk and bread. Even short sight seeing side trips are a major undertaking. Towing a small vehicle is an option, but buying a good pickup and a medium size trailer (< 25') I think is a better, more cost effective, option.
