If you're seeing "a lot" of them then it must be okay, right? Why not just go ahead and do it?
You really seem bent on talking yourself into moving forward with your plan, so here's my encouragement: Go for it.
Everybody's different and you won't know how you will feel about this until you experience it for yourself. There are some absolute crazies out there that will throw a 4000lb camper into a stock F250, hit the road, and think it handles like a Lamborghini. Then there are some who put a 1600lb popup in a DRW F350 with 19.5's and all the suspension mods, and think it's going to tip over on them doing 25MPH on a dead level road. Then there are all the ones in between.
The reality is it will be more uncomfortable than dangerous unless you do something really stupid.
