I made a few changes with this remix.

• Opened up trailer frame to make grid style flooring and tailgate. There is also a solid floor
  option to print. It fits in the same location as the grid floor.
• Moved tongue from bottom of trailer to front of trailer for ease of printing.
• Metal Ball coupler mounted to front of tongue with M3 screw
• The fenders are same as original trailer. Those parts can be found on the original trailer page as well as instructions by Jaxes88

• See updates for additional changes.

  The trailer frame Is printed with support everywhere for the railings. The tailgate is printed flat with support touching build plate.

Update 3-5-24 : Added parts for spring suspension with bearing located in wheel hubs. Uses the same axle as the original trailer (3/16 rod) cut to 100mm length. Insert the axle into the axle tube first. The bearings are pressed on to the end of the axle to be flush with the end. Then press the bearings into the wheel hubs. Be sure to install the axle in the axle tube before pressing everything on. I added holes in the trailer frame where the spring hangers attach but that is the only change to the trailer frame. The parts are attached using M2 bolts and nuts.

Update 3-16-24: Uploaded trailer body V2 to correct slight size error in right side frame rail.

Update 3-17-24: Added files for teardrop camper. Print the bare frame, teardrop floor, teardrop cabin and doors. The cabin file was about a 14 hour print primarily because of the support and my slow older printer. This is still a work in progress. I'm working on the door hinges and a hatch for an aft galley so I'll update the files as I go. The fenders can still be found on the original trailer page. The bare trailer frame can also be used if someone wants to create a trailer of their own.
