The novelty wears off pretty quickly for most after they realize the cons far outweigh the pros.
The first time a RTT sleeps in a decent wind, it will be for sale shortly thereafter!
Pros:
-It gets you off the ground
-Makes you look overlander-ish (if thats your jam)
Cons:
-Its a giant sail in the wind
-messes up vehicles COG
-messes up MPG
-adds wind noise
-ungodly expensive for what it actually is
-requires decent solid. usually aftermarket mounting solution
Yeah, theyre silly... i had one about 20 years ago when Eezi-Awn was first coming to the US, and after using it a couple times in the wind, it was sold and never went back
Oddly, i am seeing them more and more in San Diego around town on weird vehicles that dont even remotely have the rack to support them. I find it humorous
