At the point I am ready to replace my current tent it will have to be when the compressible hard tops come with an annex and are affordable. So either they come down in price, I win some serious money playing the lotto, or I get a pay raise for some serious $$$$. Until then my CVT Mt Shasta is still kicking ass as a RTT.
I think I picked up mine in 2010 or late 2009. I have certainty put it though it's tests.
It's flown off my truck while flying through the desert, 3 covers, two sets of mounting rails, 3 different heaters, a few custom made brackets for the internal frames, remachined hinges, a few patches and getting ready to replace the foam in the mattress.
We've literally have spent a good number of months in that thing. We've been in 70 mph Mojave wind storms, probably 60 rain storms, a dozen snow storms and way too many nights in the teens and 20's.
The only thing I could really see replacing it with would be a 4x4 van or maybe a custom foamy or something along those lines.
About it to go spend a week or so in my Happy Place and maybe a few other places most all nights will be shacking up in the RTT with a Big Buddy or two.
