Any thoughts on these 3 RTTs? Thinking about trailer mounting one, the two person seems plenty larger for my wife and I and I prefer as compact and light as possible. I was able to check out the Yakima in person and it seems pretty well built and breathable.
As a Tepui owner I'd recommend checking out Tepui's Baja series which are made of the same 210D nylon & you'll be able to easily switch out your canopy with mesh or canvas with their patented zipper gimp. I saw one of the new Skyrise tents at my local REI this weekend & asked to see some detailed specs on that breathability claim since it looked like standard PU coating to me.
I have an Ayer. It fits nicely on the jeep and opens to the rear. I use it solo 50% and with my 8 year old the other 50. I would personally buy one of the 56" wide tents if I was doing it over. 48 is okay, but tight, especially in driving rain, snow, anything that makes you not want to touch the tent sides.
You're forgetting about the Tepui Kukenam Baja Series (Ayer size available too). It's a bit larger than these and can be done with a mesh canopy or a lightweight nylon canopy if you're wanting something lightweight. Having seen all of these firsthand it would be my top choice hands down for a lightweight RTT. http://tepuitents.com/collections/baja-series
We have run a Tepui Ayer for about a year and a half now and absolutely love it. My wife and I, plus our dog on occasion, sleep in it just fine. It's been through all kinds of weather from clear sunny days to torrential down pours with heavy winds and it's held up great. We have enjoyed our Tepui so much and had so many people ask about it that we actually decided to become a dealer for them. I'll send you a PM with more information on the Ayer and our experiences.
