As a comparison only (it's your decision) Some parts of my setup:
GMC 2500HD,4x4, extended cab, duramax, about 6800 lb.
Lockers front and back (auto in back, electric in front)
Heavy duty top over load springs
other upgrades
NO AIRBAGS!
Winch front or back
heavy duty, oversize offroad tires
2 mounted spares - never needed even one
Outfitter Apex 8 popup camper, fully loaded about 2800 lbs.
no AC
most of the load right at truck bed ( 4 batteries,44 gals water)
