Brent,
Thanks for the Kevin update.
Personally, I love the ARB. I had the Car-Top-Tent knock-off on my 80 and, while lesser quality than the ARB, loved that one too.
It was basically the identical design, except ARB has the extended vestibule, which I love. CTT went with the truck. Still have the annex from that old tent and never used it then when my tent was 8' off the ground.
This height is much better, especially for my son. Easy setup, easy in and out, easy peasy. I am older and fatter so I wish the mattress was a tad thicker, but I think I will just lose weight and call it good.
The trailer came with the ARB, so it was a perfect fit for me and I already knew the design. Nice thing now is that I can leave the tent up, with the trailer, locked at camp and take off for a day of wheeling with the boy without having to break everything down for a cruise. That really got on my nerves.
IMO, trailer and tent is the way to go...even if I still had the 80, I would not go back to a tent on the roof.
