Just for gits and shiggles, our 5th wheel sits the truck level with it's 1900 lb pin weight plus the 140 lb hitch and 100~ lb tool chest. Empty it sits like the 1500, about 2.5" higher in the rear. Front doesn't change. If you look at my sig pic, the parking stripe under the truck is even with the bottom of the truck. Sounds like your truck is set up right. I know it's hard to not want to tinker with it but, don't fix what ain't broke! And don't become hyper-sensitive looking for something to fix. It'll drive you nuts!
