Chevy/GMC bed height

[Roger10378]

Anybody out there have a 20/21 Chevy or GMC 2500 double cab standard bed 4wheel drive. If so what is the height of the bed rails from the ground. I don't want to order a new truck if it is too tall for my 5th wheel. Nobody at the dealership can tell me and they don't have one in stock.

Cosmetic like fixing rust? (See you’re from MI).
That is throwing money away on anything that still is going to see winters in the salt belt and not even a worthwhile effort if it won’t see more salt, as everything else is crusted and rusted too.
If not rust, then I still don’t understand. You have the means and desire for a new truck and there are so many other options. From lifting the trailer to lowering the back of the truck a bit, to buying a presumably much nicer used truck that does fit.
Or am I missing something in your equation?

My 2020 CC standard bed RWD measures 59 1/4" at the rear bed corner. When I looked for new truck I was hoping the RWD would be lower than 4x4, but not the case anymore. Both measured the same bed height. The dealer gave me such a great deal back in May because of covic-19 they were having a hard time selling inventory, I bought it. It had the 5th wheel puck system, so I bought the Curt adapter for my Q20 hitch. I hooked up my Sprinter 5th wheel and started laying boards under the tires of the 5th wheel. After several attempts, I had 4" of wood boards to get trailer to measure from ground to frame the same, front to rear. I found a company in Canada that makes lift kits and bought 2 set, 1 set per axle, 3" lift blocks. Trailer still not even front to rear so I changed out my 15" rims to 16" rims and had Goodyear Endurance ST235/80/R16E installed. It was finally equal front to rear. I've toad it over 4000 miles now and it's been great. Love the truck, but it took some work to get trailer level. One other thing, I kept my 6" clearance between bed rail and bottom of 5th wheel.

If you do decide that you want a new double cab, I believe that you may wait awhile. It had been reported that GM was "mostly" building crew cabs, and I heard of someone who ordered in August that does not have their double cab. I know someone who ordered a crew cab in November that had it on Dec 31.

57 1/4 at the wheel.

I have a 2020 Chevy 2500HD Crew Cab with a standard bed. Measuring from the center of the rear wheel, it's 58" from the ground to the top of the rail. It's 21" from the bed floor to the top of the rail. The bed itself is 6' 10" in length. I assume the standard bed has the same dimensions whether it's attached to a Double Cab or a Crew Cab. I hope this helps.
