New HD truck bed rails too tall for 5th wheel

And to dispell the typical rvnet rumors, new trucks haven’t gotten “so much taller.” Unless you’re comparing to, idk, 25-40 years ago models.
You probably weren’t trying to hook an old school 5ver to your bullnose F350 4x4 or 2nd gen Ram in the 80s or 90s or you wouldn’t be complaining like this is something new.

PS, you have a small 5ver with small wheels, marketed for a 1/2 ton. Did you expect it would have a Diesel Brothers off road makeover?

There's quite a jump in height from 2000 to 2015 on a Chevy 2500. Sold my Dad's old truck or I'd measure. Just firing from the hip, I'd say at least 6" difference. On his 2000, you could easily reach into the bed over the side. On his 2015, you can easily peer into the bed over the side, but you're not going to reach anything without opening the tailgate and climbing in. Both stock height.

4wd Chebbys were typically “shorter” than their F and D counterparts thru the 70s-90s. So since you cherry picked the 2000 model year, 1 year before the GMT 800 chassis started for the HDs, you’d be 100% correct.

I can’t count how many times people asked if my wife’s bone stock 02 Duramax had a lift kit. Why? Because they got appreciably taller in 2001.
But GMs of the GMT 400 and earlier vintage aside, the height hasn’t grown much.
Remember @rhfago post comparing his 2nd gen srw to 4th gen dually? I recall same height. That 2nd gen chassis started in ‘94 and the trucks haven’t gained appreciable height since then.
Old OBS and bullnose F350s and even the 250s were tall as fck. Even the bump side and dent side Fords, aka the Highboy era weren’t short.
Bet @spectra truck is close to new 3/4ton 4x4s.
