I'm finding that in the large truck camper world....you just can't have enough truck...and similar to when I owned the ocean boat...2 more feet of length always seemed like a good idea. For my experience, eliminating weak points in my truck has always been my focus, systematically upgrading each weakpoint as they arise or as money allows.
I agree with sleepy about brush guards and winches, etc....if you need those things, get them, if you don't...it's a lot of $$ and weight. My brush guard bumper has saved my bacon already twice.
As I'm seriously saving for 19.5" wheels, I find myself pondering the idea of an F550 or even F650. I need to carry more than I do now, and I more room in the cab. The need to haul 15-20K lumber packages is coming our way soon as well. I can do that with my current truck, but not with the camper. I bought the camper to be able to live in it while building remotely....but as sleepy pointed out....the weight and maintenance issues with a much larger rig, are something to seriously consider.
I don't have good answers.
I know that overloading is bad, I know from experience...its costly and dangerous. Traversing across extensive back country areas where phones don't work...is awfully tempting to bring every tool and spare part you can fit. Awfully heavy also.....
