Stu, we are joining you in traveling by caravan! Last week we ordered one of these:
However, ours will only be for occasional use during our travels. We will still use motels for most of our nights. This is just for those times when we are deep in a national forest of national park and don't want to drive a couple hours back to a motel. Or for mild off-road outings with groups. It is only 5X8 feet, and just 44" inside height. It is low enough that we can put our kayaks on top, or use it as a utility trailer or moving van. I consider it a multi-use trailer. Deb just rolls her eyes...
And then, against 38,000:1 odds, a week later I won a free roof top tent for my 4Runner!
I think that's where I'll send Deb if she starts snoring in the trailer.
The trailer will be several months lead time, but I should receive the tent in the next couple of weeks. I look forward to trying both of them out on our travels!
