Well I went and got 1 axle. He said they were 9/16" lugs, they are not, there 1/2". Tried to put my rims on as duallies, wont work, the brake backing plate is to big. The offset on my F350 rims is too much for SWR. Only solution now is to make the trailer into a tandem, and get I guess what they call (directional rims ?). What the hell did I get myself into? One hell of a lot of work I suppose, and a lot of money.
Found out the trailer frame Mfg. only did 3500 of these trailers and only three in Alaska had to be changed, not Military at all, it was they are not DOT approved for the RV weight the frames were made for.
