Sorry, that makes sense pulling that trailer with a small truck.
Good on you.
Dang , those conduits are usually welded on.
Could you zip some welds off and slip the bracket behind the conduit?

If I was going to be torqueing the bolts, I would put a jack under to support. Will that change the final reading/actual torque on the bolt? No. But I'm lazy, don't like to do extra work. Likely the person turning the wrench will not see it, but as he bears down on the wrench the vehicle goes down. Then when release pressure to get another flat, vehicle comes back up.(More likely to see that.) Every stroke, as the bolt gets tighter, more of the force is used to compress springs before the nut starts to turn. That is wasted work.
Something else to think about; I don't know how many times I have had a helper, (confess, once I was the helper) when I have pulled a bolt to get it torqued, then hear "Need to back it off, wrench is locked" Yes, arm wrestling when the other guys wrench is 4 times as long as yours it is easy to wedge your wrench against something solid. By yourself even easier. Hold a bar or board between wrench and solid so you can have leverage to pull it out, get play, and your wrench back.
BTW, most of my life I would of turned things so I was lifting instead pushing down. I could lift more than I weighed, let alone what weight I could get on the wrench. But I have gained over 100 lbs, and lost muscle

I doubt most people even know where to find one.


Most people pay the RV dealer to install the hitch.

I'm also really curious how the wiring is routed on other trailers from the body of the trailer to the coupler and umbilical connector.


On any of mine, the wiring is just held to the frame by clamps.

Not sure how they can do it if they don't have a torque wrench either.

I used my 24" adjustable wrench and a four foot 1 1/2" sch 40 pipe...then jumped on it with my 220 lbs.
Working at the C-17 Tulsa mod center in '97. One big mil spec bolt into the wing spar had a 3400 ft lb torque. It took three 6' plus husky guys with a six foot 2" pipe on a torque multiplier to get'r done. The bolt could only be reached on top of the wing out on the very leading edge. Luckily I wasn't 6' tall.

I won't give numbers, but the torque required for head bolts on a submarine nuclear reactor cannot be reached without thermal changes, and normally only done in a shipyard.

Boeing didn't provide appropriate tools to do this wing job?

At that particular time we were still McDonnell/Douglas however musta' been ok...USAF inspectors bought it off. I do know this site was considered a field operation...not a manufacturing operation.

I decided to just grind off the one weld bead in the middle and pry the tube away from the frame so I can slip the bracket between the frame and the tube. That leaves just one weld bead at each end of the three feet long tubes. I may slip a hose clamp or something over it to make sure it doesn't pop off, and I may eventually just cut the wires and remove these tubes, and then solder splice the wires and use plastic corrugate or something like that.

They do it, all the time. Probably with an impact gun. They probably don't even count the ugga-duggas. They've done enough of them to know what tight feels like without a torque wrench.

Folks have to keep in mind we're not building a Formula 1 race engine here. We're assembling a weight distributing hitch with big beefy castings and large bolts. Close enough is close enough, and there are ways to get close enough without having a torque wrench.

If you want to fret about having all the bolts tightened to laboratory accuracy that's your prerogative, but again, close enough is close enough.
