Hey happy turkey day. I move the rear to the front the front to the middle and replace the middle tires and put the new ones on the rear. I believe this is overkill but having a couple of blow outs on the rear axle I want the new ones on the rear.
I put up a 30 x44 pole barn. 6 inches of concrete 4500lbs wire reinforced. 16 ft ceiling with 8ft florescent lights down the middle an 3 ft off the walls, all the light I need. Each row is on its own switch so all don't have to be on. Lots of power outlets. If you can put in a dump station 50 amp power dedicated to the rv. Good luck.
I had the same problem with my goldwing. What I did was put 2 6x6s under the rubber stoppers of the rear gate. I bought a tri fold aluminum ramp and extended the ramp. Works for me. PS I also use a strap to hold the ramp to the gate so it don't kick out, just a little more safer. Good luck.
