I'd go for it but I'm biased haha. You can beef up the rear with some progressive springs like Deaver, or Atlas. I personally run deavers +3 which eliminate the stock lift block and sit about 1 inch higher overall. Truck sits nice and level loaded with 600lbs+ worth of gear for trips. They also improve the ride considerably on and offroad. Stock springs should do well for a while as well.
Feel free to check out my build thread (links in my signature). My truck is built more for 2-3 day trips at the moment but I'd have no problem taking it on an extended trip if I had the time!
