Clearance is an issue. I'm using a 2x8 all the way across the front of the bed. I backfill that in the front bed wall recess with 2 pieces if scrap chipboard 12x1x4. I needed that to open the truck rear doors. I attached to the 2x8 2 joist hangers so I can run a guide rearward on both sides against the fender well. I put a short (8"?) piece of 1x4 on both sides of the tailgate opening with a shorter piece of 2x4 screwed to it so that it is captured behind the tailgate opening. I wrapped the guide boards and the tailggate spacers with astroturf. I needed the tailgate spacers to keep the camper off the truck. I use the rear bumper plug and wanted to be sure I didn't crush the power cord in the tailgate opening if the camper moved. I have my entire bed covered with 5/8" plywood. I use a full coverage rubber bed mat on top of the plywood. So far I haven't seen much movement from the camper.
The jacks are an issue I don't think I can solve, or at least it may not be worth the effort. They have maybe 3/4" clearance with the fenders when loading. It's a pretty high pucker factor. It's a foot or so when backing up that it gets so close. I just go slow slow. I have looked at ways to extend the dually swing outs. If I just use plate aluminum sandwiched over the attaching bolts of the swing out bracket and the jack I won't be able to open the truck rear doors when they are swung in. I suppose I could just swing them out whenever I need to open the truck doors but... I have looked at maybe using square tubing between the jack and the camper to extend the jacks out and not interfere with the doors. If I do that I will have to talk to Bigfoot about what the jacks are screwed in to. Not sure if it's a wood block or a piece of steel.
There is an opportunity here for Bigfoot to step up and offer a solution to mount the jacks farther out.
The Torklift tiedowns. When I bought the Camper, the previous owner threw in the Fastguns. I mounted the Torklift tiedowns to the truck I owned at the time....2016 RAM 3500 SRW. The front tiedowns were a beast using the fish wire and a bolt that should have been longer. Needle nose Vise Grips saved me. When I bought the 2018 dually I assumed I would need different rear tiedowns, but no, I needed new front ones. Thankfully they didn't require a fish wire.
Fastguns...they will rub the fenders without some kind of modification. I talked to Bigfoot about using machinery eyebolts in the Bigfoot tiedown anchors. They were fine with that, so that's what I'm using. They pushed the Fastguns out about an inch. I also talked to Torklift and they said it was OK to drill another hole in the frame tiedown extensions. I drilled a hole about an inch farther "in" on the extensions so that extends them out some more.
Hope that helps. Keep us posted,
