Truck campers , who's got one.pics?

[biglump67]

How many people here have a slide in truck camper. How do you like it. Does it effect gas mileage and make the truck blow around alot more ? I am thinking of selling my van, and buying an old longbox truck and camper.
I want a camper that will sit inside the box, not the real big 11 or 12 footers.I would buy an avion even though they hang out the back, they are just too cool. I want to be able to still use the trailer hitch, so I can tow a trailer with cycles or a dune buggy.
The campers usually weigh about 1500 lbs, would a 1/2 ton handle that ok, if the rear springs were beefed up. I figure the VERY MAX, I would pull carry combined would be 7k lbs.
I figure the trailer about 1500, buggy 3500, camper 1500. If we take the trailer out of the picture is a 1/2 going to carry a 1500 lb camper without hurting anything in the rear axle?
Thanks, John
