got the trailer back... it's not 100% done, have fenders to swap out, 2-3inch gap between fender and trailer body... I figure this will give it a cleaner/hug on the fenders, and I won't have that gap to drop stuff down... I'll go back when they have it ready... but for now, it's coming home.
things I learned...
the 6x5.5 hub's, are not toyota friendly, had to add wheel spacers with lugs to get them to be centered... worked like a charm... extra $100...
the lock - n - roll trailer hitch... still have to find a 1/2 inch dia x 3.5 inch hitch lock
simpler is still not way cheaper, just cheaper... went from designing a 2x2 frame to bolt the box on to, to just a bunch of angle iron.
don't run around too much...
axle and wheel choice... I wanted to go 3rd gen wheels... but can't in the end... goal is to have it follow the truck in the tracks... but they didn't have access to a 59inch axle, so I went 61inch thinking I have spacers on the truck... but wheels don't work on trailer hubs, adding a spacer fixed the issue. but now I'm 63.5 inches, with these rims, I'm 1inch less... so 62.5... and my truck is 59 + 2.5inch spacer (1.25 each) and I'm sitting 61.5 wheel track so trailer is 1inch wider center wheel track than truck... oh well...
