If you run a tape measure from the floor of the bed to the top of the bed rail; what's it read?
Of course, I measured it before I did it ... bed is 21 1/4" deep, Lance sidewall is 20 1/2" ... that means it needs the rubber mat - so when I measured it, still leaves - technically - 3/8' too deep.
I lowered it onto the bed mat, and it seems more like 3/4" -- but could be the "hanging off the jacks' and could be a slight taper between the edge wall and the interior sidewall - who knows how perfect these get assembled.
SO, when I add the 5/4 decking, it looks like it gives about 3/4" to an inch. In any event, the camper needs lifting -- and I'd not leave it laying right on the bed rail anyway ... even if it matched exactly.
Main thing here -- look at your camper before you drop it into the bed, and watch it how it lands. Not sure how much clearance other campers need, as I only have the Lance 845 ... it's a 2008. Not sure if newer models are different. Know one thing, I'd not want the side wings hanging 3000+ lbs on the bed rails ...
Lots of other little issues add up to a bit of modification if you transition from a older truck to a new truck and want to use the tie-downs and other components. We makes numerous mods to the set-up off my 2003 GMC -- but it works and we didn't need to buy all new stuff - we did fabricate a rear tie-down tho. BTW: The step-rails "almost" fit from a 2003 to a 2105 GM, we just elongated the bolt holes and it matched right up.
