Remember this when looking for a truck.
A new truck could (and will) spend time being repaired.
Some one can buy a truck with 115k and drive it another 115k and sell it to someone else who puts 5 miles on it and it breaks down.
These are your 2 most likely users of a forum.
The guy with the new truck that does everything he tries and the guy who has the trouble free used truck will rarely show up on a forum to talk about their trucks.
The guy who goes to fold his tow mirrors and they don't...we had alot of that type for awhile. RAM was terrible. But, yet there is another guy happy as a lark with powerfolding regular mirrors and he has never once power folded his mirrors.
When you come to a forum...issues are daunting sometimes.
The best you can do is be honest with what you want.
Research facts about the trim you want and the options you want.
Be realistic of the expectations of your truck. Remember there is a reason for Hemi and v6 or lockers and open diffs and 2500 and 3500 trucks.
And then look at the issue with an open mind.
