Hate to burst you bubble but the CVT's, Tepui, CTT's (I even think the ARB's) and what not are all made the same. Some may have a different ladder system and color but for the most part the construction is the same. I wouldn't be surprised if they are all made in the same factory in China.
OP, I think you'd be much better served spending a tad extra for a used Eezi Awn, Hannibal or similar higher end brand. If you are opposed to used at least find one of the lower end RTT's that run YKK zippers......your fingers will thank you in the end.
