Sorry to hear... in the end your going to have to weigh your enjoyment of the truck when it is on the road versus the cost/aggravation of the repairs it needs. Smart move on the warranty BTW, wish I had been able to spring for one when we purchased ours. Was going to cost ~$4000 if memory serves.

I love these things and nothing you mentioned sounds like a deal breaker for me, but we all have different needs/wants/desires so... it's going to be a decision you'll have to make.
