Welcome to the TDR!, good first post,Your truck is overloaded by a substantial amount,this is why it puts a huge squat in it,the 3500 is the truck for carrying slide campers,IMO. Dont take this the wrong way,im not telling you what to do,but your endangering yourself/family with that rig,it isnt going to handle well,it is at the limits as far as being safe,and the tires will run very hot,even at 80psi. I wouldnt go far with that rig,and not very fast either. Your wet weight will be over 3000 lbs on that camper. As other will say,you can put airbags on it,and it wil sit level,it still wont stop well,or be able to manuever if needed like a 3500 dually would.
