Really? What is your actual HAHA box opening height to the top lip? I just got out of a 2500 and haven't changed my stinger yet (adjustable PP for HAHA). I went out to the garage and measured where I had it set....6" drop. I try for a stinger height at 15" from ground to top of stinger bar while installed in the truck.

Here is a cheat sheet I use. Substitute you own coupler height, but don't forget the top inside edge of the box opening is 5 1/2" below the top of the coupler...

Hensley Arrow calculations.docx

And remember, there will be some squat of the rear of the truck.

Also, my calculations take into account 16" tires and wheels (raised the trailer 1/2") and 900 - 1050# tongue weight depending on toys loaded (bikes and bike rack on tongue) and stuff in the bed of the truck.

I'm planning to re-install the batteries and hook up to the Silverado. Checking the height differential from front to rear should indicate how much needs to be cut off the stinger drop. I found a local welding shop that will handle the reduction for a lot less than ordering a new stinger from Hensley. I know they have exchange program, but I'm not the original hitch owner so in order to take advantage of a Hensley swap (I never asked how much that would be) I'd have to purchase a Hensley extended warranty for $500+.

I also noticed that one the trailer is set up to ride level, it looks as though the Hensley torsion bars will ride very low to the ground? I never noticed it before, but there is no doubt that when hooked up to our Suburban, the trailer obviously was higher at the front.

Any thoughts about this?

I don't worry about the ground clearance. I've never measured it, but I'd guess 6" or so. I've only (barely) dragged the bars ones coming up and over a raised sidewalk at a gas station. It was an unusual situation where the station was in a hole, relative to street level, and the sidewalk was maybe 6 - 8" above street level.

Measure and weigh carefully. so you only have to weld once. The issue of Hensley only having two inch increment is why I got a "PP for Hensley " stinger. But they are like hen's teeth.

Thanks Rich. But what is a "PP for Hensley" stinger?

Every once in awhile, Sean, at Propride, makes up a small batch of adjustable stingers to Hensley fitment. The end that goes into the hitch-box is dimensionally different between Propride and Hensley.

See it here:

Our trailer is winterized, so we haven't taken it out yet. But we're looking forward to our first trip with our new tow vehicle.

Here's a pic:
You are a bad person. I've been obsessing about the GMC Denali ever since I saw yours. I bought the first Ford product I've ever owned about 18 month ago (an F-150 Ecoboost) and it's "fine" ... but not in the same league with my old Silverado.... and not with the luxury features of this GMC.

I want it. and here's what's really funny, my name. Paula Ford

We just decided the 18" wheels were fine, and it saved us a little money off the final price. Down the road, it will be cheaper to replace them too!



Good Luck!

Does the truck have a rear vent for heat / AC?

My Silverado Duramax Crew Cab does not have rear heat/ac vents. But then, I don't plan to ride back there!

OP-
We found the GM / Chevrolet to be considerably quieter and smoother at towing speeds (60-65mph) than either the Ford or Ram...any of the diesels have more power than you are likely to ever need!

Do GM diesels have the similar emissions as the Ford 6.7L? Any partial engine slowdowns etc due to low DEF or exhaust gas sensors?

This is not too far from me. It's been advertised for over a month now.

Nice rig

So, what year did the exhaust brake come out on the 2500? Also, when did the quite diesel engine come out. I would like to find a clean used version of the new one. How far back can I go?

I use to have the 06 F250, had all the problems, etc. I never bought anything that expensive and for it to leave me in an intersection twice was just unacceptable. Never again.

Does the Airstream umbilical plug fit the Denali socket?

I finally put my new 2500HD in front of my Airstream to check the hookup. I found it impossible to fully insert the trailer plug into the truck outlet. The prongs inside do make contact, so I was able to check out the electric over hydraulic brake hookup (seems to work fine as far as I can tell without actually towing it).

However, the prongs don't seem to actually slide together (at least not with normal insertion force), so any jiggling of the umbilical cord causes loss of contact. It worked fine with my old F350.

A late model "standard" plug slides into my Denali just fine - see comparison pictures attached. I've used my truck with a utility trailer without problems.

Maybe I need to push the airstream plug in harder (risk bending the pins), or else cut off the moulded airstream plug and put on a replacement. Before I do that, I want to check if anyone else has run into this problem.

Thanks!

Gwmc, mine is harder to push in than my 05 was. It seems to be getting easier after use. I have always been able to fully insert the plug and make sure it was locked in. Pulling it out I thought was going to pull the receptacle from the truck but it stays in place. Tighter fitting for sure on the 15 Silverado.
