Truck Camper On A 1/2 Ton?

[Cadillac Kid]

Hello,

I have been wondering this ever since I bought my truck.
The truck has a full camper in the bed. It's not a cabover camper, but its not a shell ether. My truck is basically optioned with all of the camper special options, even though it isn't actually one (I wish). Dual tanks, dual batteries, HD front and rear suspension and brakes, ect.. My truck is a 1/2 ton but it has 8 leaf springs on each side of the rear axle. 7 normal leafs and 1 overload spring. There is a 73' 3/4 ton Camper special in my neighborhood that only has 7 leafs per side. Do I basically have 3/4 suspension? I know the axle is different.
What I want to do with my truck is put a cabover camper on it at some point, is that going to be possible with my current suspension setup, or will the truck be sagging and not be able to accept the extra weight. The camper I will most likely get will be from the same vintage as the truck. Not some new fangled heavy lance camper with all the bells and whistles.. I see plenty of truck campers on 3/4 tons and 1 tons, but never on a stock 1/2 ton.
What is the scoop?

Thank you
