So...I don't disagree with you; just remember 2 things a) the sample size and b) this IS a thread about problems with the JB tent.
a) There are several posts about problems and also several saying their problem was resolved...out of how many tents sold worldwide. Granted, not everyone with a problem is taking it to a forum (or this one in particular) but the same can be said about favorable reviews as well.
b) The internet being what it is and forums being what they are, people are generally posting up problems looking for help, guidance or reassurance. That means that a lot of threads have a "negative" connotation. If I posted a thread about how great my JB tent is, it would get nowhere near the number of responses as one that was less than favorable.
Personally, I think the OP has really shared a cautionary tale that we should all heed at the time we take receipt of a JB tent, or any product for that matter. I'll freely admit that I probably didn't inspect mine as well as the OP did (I was at a dealer's shop and he was installing it); but if I had it to do over again, I would inspect it closer and not taken reciept if it had even the smallest issue (or I might have haggled a price reduction). In my scenario that would have worked well because the guy had 10 more sitting in boxes; so I could have looked for one that was defect free.
@dstock please don't think I'm picking, it's just that if JB was a serious contender on your list, don't rule it out. Just know what things to be aware of and look for. Like
@1pieceatatime, this is my only RTT ever; I really agonized and vaccillated extensively before finally taking the plunge. I honestly couldn't be happier with my Evasion and if it's what you want, go for it and camp the heck out of it.
