My wife and I just did a 2 week camping road trip with our kids: minivan with a tent trailer. It has served us well since we got the tent trailer several years ago, but the limitations of both the tent trailer, as well as the minivan as a tow vehicle are getting to the point of being a nuisance. The van wasn't purpose-chosen as a tow vehicle - it was what we had when we decided on a trailer, and that dictated we look at tent trailers. Difficulty climbing steep mountain passes is one of the issues, then the whole set up and take down of the trailer gets to be a real burden on short stop overs, espcially overnighters. Upgrade time, at least for the camping rig, is going to come sooner rather than later for us. Starting with the trailer, we agree we both want a fifth wheel. Road trips are our thing, and with bigger trailers, the stability of the fifth wheel is a huge plus. That means from a practical perspective, we need at least a 3/4 ton to have a good margin when towing (don't want to be towing at the limit like with our minivan). New, while nice, is out of the question budget wise. In fact, we haven't even decided on a budget yet, but I know it won't be for the cost of new: either trailer or truck. And so I come here with questions related to one half of the equation: the truck. What am I looking for, besides 3/4 or 1 ton? Diesel powered, can be either manual or automatic, crew cab or extended cab, probably long box, though I understand there are special hitches that eliminate clearance problems between the trailer and cab for short boxes, and it should be reliable. So then, what do I look for? Anyone here have experiences, good or bad, with Ford, GM or Dodge diesels? Are there certain transmission or engines I need to steer clear of? I am already aware of the 6.0L PowerStroke problems, the poor fuel economy of the 6.4L PowerStroke, and the host of issues surrounding the DuraMaxes with the engine codes LB7, LLY and the not quite as bad, but not quite good LBZ. Looking at used pricing and mileage, 2008, plus or minus a year looks to be my sweet spot. With the Fords, that pegs it to the 6.4L, and I see market pricing on those are far below the GM and Dodge trucks. Dodge is less, but only slightly so overall in pricing, than the GMs. The truck would be an addition to the stable, and not a replacement for anything. It will also likely see other duties besides trailer towing in the future in the medium term as we eventually plan on moving out into the country. Would love to hear from anyone with diesel pickup experience.
