2500hd Tow Crusader 360BHS

I have a 2015 Chevy Silverado 2500HD with a fifth wheel towing capacity of 14000 and a GCWR #20500. The camper's dry weight is 12120. I still should have almost 1800 of room to load junk.

My understanding is my limit is for both truck and rv is GCWR# 20500. My truck weighs 6525 and rv 12120 (both dry). I have to be below the hitch weight and towing weight. Everything in the truck and rv on top of the dry weight has to be below my GCWR.

If my thinking is off can you explain.

20,500 minus 14,000 = 6,500 truck weight. If your wet and loaded truck with all people, pets, tools, options, 5er hitch, tank full of fuel, campfire wood, whatever, weighs more than 6,500 pounds, then your tow rating is less than 14,000 pounds.

That's true only when your 2500 grosses less than 6,500 pounds before you tie onto the trailer. But the CAT scale will prove that your wet and loaded 2500 weighs a lot more than 6,500 pounds.

That's only half of the formula. If the combined weight of truck and trailer is less than 20,500 pounds, then you won't exceed the GCWR of the truck. But with your SRW tow vehicle, GCWR is probably not your limiter. GVWR of the tow vehicle is probably your limiter.

Again, that 6,525 pounds dry truck weight is meaningless. How much does the truck weigh when loaded with people, pets, tools, options, 5er hitch, tank full of fuel, campfire wood, and anything else you have in the truck when towing? Subtract the weight of the wet and loaded truck from the GVWR of the truck and the answer is the max pin weight you can have without being overloaded.

So for a WAG example. Let's assume a wet and loaded truck weight of 7,500 and a wet and loaded trailer weight of 13,500. A 13.5k 5er is probably going to have pin weight of about 18%, or 2,430 pounds. 7,500 truck weight plus 2,430 pin weight = 9,930 GVW. So if those estimates are correct, then you can tow that 13,500 5er without exceeding the GVWR if your GVWR is at least 9,930.

Caveat: Pin weight of a medium-size 5er with GVWR around 13,500 pounds will vary from about 17 to 22 percent of gross trailer weight. If you fall in love with a 5er that has 22% pin weight, then that's 2,970 pin weight instead of 2 430, or 540 pounds more GVWR required of the tow vehicle.
Back to the GCWR to apply our new weights. If the wet and loaded trucks grosses 7,500 without the trailer, and the trailer grosses 13,500, that's 21,000 pounds GCW. Oops! Your GCWR is only 20,500, so you're overloaded. So get rid of 500 pounds of content in the trailer, and you're right at the max of GVWR and GCWR of your tow vehicle.

Not off, but incomplete. Never use dry weights for any estimates when matching trailer to tow vehicle. Use the GVWR and GCWR of the tow vehicle, then use realistic wet and loaded weights of the truck and trailer. Ignore GM's unrealistic "tow rating" and "payload rating", and use GVWR and GCWR minus realistic wet and loaded weight for truck to determine your realistic tow and payload ratings.

The dry hitch weight is under 1900. They say you add 600 to the camper with all your stuff. I have a wife and 2 kids (5 and 7). We don't weigh all together 500 pounds. That would leave almost 1200 pounds.

Is your truck a gas or Diesel? If its a gas then smokey wren his truck could very well weigh 6500lbs. I have a reg cab 2500hd gas and it weighs 6300lbs with me, my wife daughter and full gas tank ready to camp. (That's before the 800lb golf cart though).

Well, yeah, but most people have CrewCab 4x4 tow vehicles, so that's the people I usually address my answers to. And if they have a diesel engine, my estimate of wet and loaded truck weight may be too low.

My '99.5 F-250 CrewCab 4x2 diesel with 8' bed grossed about 8,000 pounds when wet and loaded for towing. Just me and Sweetheart and Puppydog, plus 5er hitch and a toolbox full of tools. The new Fords weigh a few hundred pounds more than that. Subtract about 600 pounds for the gassers. Subtract another few hundred pounds for most GM pickups that are lighter duty than comparable Fords.

You couldn't pay me to tow 13,000+lbs with a gasser. You might be ok with the weights but IMO the 6.0 just doesn't have the grunt to pull 13,000lbs all over the place. If you're just doing the weekend trip stuff and an occasional week trip in the 500 mile range then it's doable. But if you're wanting to head out for a long trip covering lots of varying terrain then you may begin to hate all the revving and low mpg's that the 6.0 will give you.

I figured you were thinking of a CC 4x4 diesel that's why I pointed out that if he has a gas truck it can't weight that much. I have a gas crew cab 4x4 dually that I bought recently and I have yet to weigh it. I'm real curious to see what it weighs.

I agree the gas truck certainly don't pull better than diesels but its hard to beat the hassle free ownership and much cheaper up front cost to get the same truck.

I have owned and towed with 3 diesels for 20 Years and no way I would have been able to tow my units any cheaper with gas trucks.

It's all relative. Pay more upfront, get more on trade/sell. Diesels get 2-4 mpg better than gas towing. Nobody keeps their truck forever, we all eventually sell or trade it. This fixation that you need to make up the extra cost of the diesel is irrelevant. You recoup when you sell/trade.
