Need advise on which new truck - 1/2 ton or 3/4 ton?

It also depends on where and how far you tow. If long trips and mountains are your thing, go bigger. If not you may be fine with what you have. The 3/4 trucks will tow better and be more stable as stated. They are also bigger. This can be a plus or minus. I went bigger and my camper is less weight then yours. Took one trip to disney , i wanted the power to pass and stop faster. Was i fine with the half ton yes. Was i happy, no.
