yes the actual width on the inside of the bed is narrower the a regular truck bed, but this particular bed is the same height as a regular truck bedThey are typically a little longer and narrower on the inside, but if it covers it, go for it! Also, the sides are taller, so the camper shell will stickup above the roofline and look goofy, but function over fashion, right?
might be hard to find one to work with 8' bedYou could find a "small truck" they should be narrower
It doesn't have to fill the whole bed lol. The last truck camper I had had a good 6-8 inches between the bed sides and the camper. All of the companies have different over all widths inside the bed. Measure what the max you can fit in and start looking. Having an inch or two on each side will make it easier to loadmight be hard to find one to work with 8' bed
And my wife would never agree to it, which makes me want one even more!
