Yeah... GM calls their 6' 6" bed a std bed so it is what it is. I have no idea why they want to be different and cause confusion.
As mentioned GM has the longest (C/A) cab to rear axle dimension which can eliminate the need for a slider especially with a newer trailer with rounded/notched front corners made for short bed trucks.
Best 5th wheel hitch for a short bed chevy ??
Of course answers will be what ever the person replying has just like which truck is best.
There are several good fixed 5th wheel hitches on the market for a 10k lb trailer. Of the top brands .....one isn't better than the others. Some are more popular than others depending on which website we look at.
I like the larger Reese/Pullrite/B&W/Curt. Each of these mfg has more than one hitch to choose from. Your choice there.
I would check with the rv dealer....hitch installer or mfg.....other same GM truck and same trailer for their input if a slider is actually needed.
I've seen more than one short bed GM owner buy the heavy SuperGlide then sell it after one summer cause it simply wasn't needed. A non slider had much less maintenance which they said was important to them.
Check your combo out
