Ok. I should have done some more research. I'm leaving January 1st and moving full time into the Roadtrek. Finalized this decision around two months ago. Was originally going to wait a few years and just travel by motorcycle but circumstances have changed. No excuse, just an explanation.
So I need to get a trailer. The place I found: http://www.cargotrailernj.com/ will make a trailer in four weeks (they claim). I can chose the size but not much else. Torsion bar axle sounds like the way to go but I don't think it's an option. At least they have drop axle's. Before reading these posts I was going to try and pack light. Now I'm thinking more weight (below it's rating) will make things more stable. I also was going to have the seller install four D-rings at $35 apiece. Forgot about E-track but now I'm not sure I have time to install that properly before I leave. Just found out about these WD hitchs. Looks like I can add that later as well. As far as seeing the trailer in the mirrors I was thinking of a rear facing camera and planning ahead while driving to minimize backing up.
I just want to say here that this forum is a great resource. Hope in the future as I learn more I can add as well as take from it.
Thanks.
