We have a lot of people come through our shop wanting to restore old RVs. Once they get into them, they generally start finding issues that they were unaware of, and the project is often resold at a loss. We've even had the same projects come to the shop over and over with different owners. Since you're capable of doing your own repairs, and this isn't your first rodeo I believe you can make this work out to your own satisfaction, but it's the seemingly "little" things that cause most of the grief in these projects. Electrical issues are a big thing, I'd suggest you rewire everything for safetys sake, and plan on upgrading any appliances you end up with. Roof and body leaks are often a huge issue as well.
Ok I’m hoping to get some advice on my trailer project. Got it in my shop and up on jack stands finally. So plan of attack is axel and frame repair first.
So what I have is a 3500 pound 4” drop axel which sits on top of the springs. If the axel can be mounted under the spring pack, I gain 4” of frame and body elevation. What I have in mind is remove and put on saw horses clean off rust, repaint and disassemble breaks and assess repairs to the electric breaks. Unknown at this point. My idea is to have a shop weld new spring perches on top of the axel just opposite of how they are now.
Along with new spring perches there would be new u-bolts as well.
Next problem is the frame, more precisely the tongue and forward part of the frame. First off a picture of the frame just forward of the body.
It’s not as bad in the picture but this is a light duty box frame 3.5 x 2 inches and it’s just folded with out welding. The weight is off it at this point but when tongue weight is on the jack this is slightly more open. Pretty light duty.
When I lifted the trailer so the front of the frame is suspended the tongue dropped maybe an inch or more. I have not put a straight edge on it yet. So to compound this problem for repair there’s a drop floor at the entrance door.
If you look this is where the drop is scabbed on at the front side, then extends back 4 feet and is a mirror image for the reattachment to the frame continuing to the rear of trailer. What I’ve thought about is to get a piece of 2x3 box tube, schedule 40 or maybe schedule 80 (I think 40 would be adequate) and follow the frame from in front of the axel spring perch forward to the hitch. Obviously a bend with an angle to match the original frame. Just lay this under the existing frame and fish plate with pieces of 4” flat strap. The end result would be a frame of 2” x 6.5” married from axel to hitch.
The drop floor beam will need to be cut out and this new under frame will do the same support of the floor. The opposite side frame rail does not have any drop to it. Just a straight shot.
As near as I can figure is when the 2 ladies were bringing the trailer up on the Alcan Hwy they at one point had backed up and not realized that they had jackknifed the unit. Not realizing what was going on they put the pedal to the medal. This ended up ripping the folding step completely out from under and a little other damage, but, at that time it put side stress on the frame.
So please some thoughts on what I have laid out, or more suggestions. These repairs need to be done before any time is spent on the restoration of the trailer.
