Though no one answered my question directly, I tried the app and it says that with a 2007 Chevrolet 2500 HD 6.6L LBZ, I can tow 1,700 lbs with a 5th wheel. I tried it three or four times.
Wow! I am WAAAYYY over that! ;)
It looks the the GCWR for your truck is 22,000. What is the GVWR and your GVW and any additional weight?
GVWR: 9,200 lbs., GVW: w/o passengers with full fuel (100 gal.) 8,180, 420 lbs. of passengers, Rear Axle: 4,000 lbs., Front Axle: 4,200 lbs.
I don't carry it full of fuel, but that was what I weighed it when I was pulling the Bumper pull. 70 gallons is about what I will fill it up when I hit a truck stop.
I ran your numbers: GCWR - 22000, GVWR - 9200, GVW - 8180, Passengers - 420
With 5th wheel checked, max 5th wheel tow: 2000
Without 5th wheel checked, max 5th wheel tow: 3000
How well does your truck tow the 5th wheel going up a 3-5% grade? I suspect the truck's GVWR and rear GAWR is well overloaded. I'm fascinated. Maybe we should continue this conversation via PM.
I know what the calculator says and it makes NO SENSE. :-) Grades can slow it down, like any unit, but there is not really a limit on how fast I can go if I pour the coal on. The hardest pull I had was coming out of Salt Lake City basin headed north. Though I don't have an EGT probe, I know I was pretty hot. Yet, even then I didn't have a problem maintaining 60-65 mph. I am not chipped, but do have aftermarket air intake and a aftermarket exhaust. I have pulled over the Rockies twice with no problems.
Yes, it is likely the GVWR and GAWR is overloaded. Next time I pull I am going to hit a scale like I did when we pulled our Travel trailer.
