The lighter camper is the better choice.
As shellbackcva59 points out, the camper will weigh a few hundred pounds more than stated in the factory brochure.
Ranger Tim's advice to weigh your truck is right on. You should do this ASAP.
Quite frankly, I have had bad experiences being over loaded.
Even with the lighter camper, YOU WILL BE OVER LOADED.
The camper weighs more than the factory says it will. Add water, propane, food, clothes, gear, and passengers and you will be 500 to 600 pounds over your trucks GVWR.
IF you have suspension mods, shocks, timbrens or air bags or springs, get proper tie downs, a rubber bed mat, and leave the tail gate at home, you will probably be okay.
I am carrying a 1090 pound pop-up on a F150. My actual camper weight is 1300 or 1400 pounds (I don't remember). The point is, my camper is heavier than the sticker on the back of it. They are all heavier.
Get the lighter camper. Weight you truck (and your truck/camper). And do some suspension mods.
Good Luck.
