I have a 1999 Ford F350 DRW PSD and a 2004 S&S 8.5. When I bought the truck back in '07 for this TC it was set up for a 5er. I didn't need the rails, so I pulled them. I also lucked out with Air bags already installed w/onboard compressor and in-cab control. They work GREAT to eliminate the "TC Waddle" running down the road.
What I don't see anyone talking about is the cab over clearance. When I first loaded the camper I had 2x4 flat for spacers. The cab over just cleared the cab roof marker lights. I very quickly learned I needed more clearance as the frame flexed enough to crunch the clearance lights at times over bumps. I now understand that with the intro of the Super Duty Ford changed what use to be kind of an industry standard cab height.....so some TC's need extra spacers in the bed. I went to 4x4's (actual 3"). There is more to that for another time.
Bottom line watch the cab over clearance height. It’s not a big deal, just need the right spacing. Depending, of course on the height of your hitch rails, I am pretty sure you could notch the spacers to fit over your rails.
BTW - I lucked out with a great truck & TC combo. My low milage truck just purrs and doesn't seem to make much difference with or without my Utility trailer, with the motorcycles inside, or the boat!
We love convenience of traveling with the TC!
