With the 1800 lbs. weight on the rear axle it may shift enough weight off of the front axle to make the coach wander while going down the road. I would go with a dolly or trailer.

It's air suspension and the tag is adjustable. Possibly with the tag set to 10,000 lbs it could make up the difference of the steel structure and car weight located about 13' behind the tag. Right now I can't quickly get my head around the lever arm math.

Even though the suspension can be raised 6" with modification that would be an very poor choice for traveling but works well for air leveling.


Don't know much about MH, but a lifetime of messing with trucks I always found a rougher ride when some axles maxed out, while others where unloaded.

Not the greatest design for my unit. Front axle is maxed at just under 14K, back axle is maxed at just under 20K. I wanted to increase the 5K tag and reduce the drive weight but can't with the front maxed. And if I emptied the cargo it wouldn't help much.

I suspect that the stability and safety of a RV is compromised with a car on the back. Probably is fine for normal traffic.

But my red line is liability: In case of a major issue my fault or not I don't want to be standing in front of a judge explaining why my RV doesn't meet his state requirements. Also why I recommend aux brakes on a toad.

I have no experience of changing the suspension the air pressure. However the ride is better than any non air suspension RV I've been in, don't know about Class B types. It's also better than any pickup truck I've been in towing or not. Plus with the rear engine significantly quieter to drive.

That’s 1800 lbs off the rear, on 3 DPs over 120+K miles. Takes 700 lbs off the front axle

Maybe you could trade your current Class A for one like this. The owner stated that it would also take a Smart Car.
