Took the trailer out for it's maiden voyage. About a 1200 mile trip to northern MN. I drove through rain for about 5 hours and was pleased with the water tightness. Unfortunately both doors were tight afterwards. I'll have to take both off and rework them to have larger gaps. I found it easier to get in and out of the large back door rather than the side door. I've pretty much decided to build a pair of lightweight foam barn doors for the back. The current single door is too heavy and too big.
The Yakima racks served nicely as places to tie an awning to and for a clothes line. I'm thinking of adding running boards along the side to have something to stand on while tying down the boats on top.
Sleeping in it was better than a tent I must admit. It was quieter and darker in the morning and no setting up a tent in the rain. I had a 4" foam mattress along too which was more comfortable than sleeping on the ground.
I was monitoring the mileage along the way and figured I got 5-15% worse mileage. The weird thing is the best configuration was with boats on the trailer (I also tried them on the van instead) and 70 mph rather than 55 mph! I drove a mix of interstate and secondary roads and consistently got as good or better mileage at 70 mph than at 55 mph with the same configuration. Don't know what to make of that, drag is supposed to go up with the cube of the velocity.
Anyway, a good trip and it was nice to have something to carry all the gear.
