Hi Robert,
I'm up the road in Chandler. You've come to the right place. Between Ray and the many other followers of this channel there isn't much about a fifth wheel that somebody here hasn't already fixed.
Welcome.
Ken

Thanks, Ray. You probably hit it on the head. My inverter is 3000 watts. More batteries it will be. I used your videos to make my own cables, so I'm sure they're fine!

Having attained geezerhood, I found that I'd rather not lift heavy stuff into the back of the truck (like a generator). Several years ago I installed a lift gate, the best mod I've made. I had to choose between that and a 5th wheel gate, and I've never regretted the choice.

I'm with RV Solar. Take the rig to Mexico twice a year for a wash & wax. Otherwise I need 2 days recovery time.

I've long since forgotten where I learned this, but the way I do it is:
finger tighten all of the lug nuts, use the tire iron to snug them down in a criss-cross pattern, torque them down in a criss-cross pattern. Since I have all OEM wheels, I use the torque setting in the owners manual. I'd follow Ray's suggestion for finding the torque setting.
