[Peterbilt359]

Hello I'm new to the site my name is Chris and I'm starting a build on a 1984 Peterbilt 359 long nose. Were building a 24 foot box and would like to install a slide into. Were just not sure how to go about it meaning if we should buy a kit or find a old rv in a junk yard and remove one from it. I have no idea were to start with that as far as the box were building out of 2x2 square tube 1/8 wall and roof bows out of 2x3 tube 1/8 wall. The floor is built out of 3inch channel and 4x2 3/8 wall sill rails. The box is very strong and starting to cut windows and door in but relly want to put a slide out in. Anyone have any ideas thanks chris
