herk7769, maybe you can help me before the middle of October.
I ordered a new 5th wheel from the RV Show in Hershey and it will be in soon. Now I am told I can tow this new 5th wheel, I am going to give you the info on my truck and the new 5th wheel, so here go,s....
.................................................. ..................................................
I have a 2008 chevy heavy duty 1/2 ton it has a 6.0 gas engine, 4:10 rear and a 4 speed heavy duty trans, heavy duty tow package, factory brake controller, now GM only made this truck for two years from what I understand, in 2007 it was called the 1500 HD and for 2008 the name had changed to Vortecmax the truck has a 10,500 lbs tow rating.
.................................................. .................................................
The 5th wheel that was ordered is a 2013 Open Range" light " the model is a LF297RLS, hitch wt is 1,265 lbs, GVWR is 9995 lbs, UVL is 7465 lbs.
Do you think I will have an issue with this set-up.

As I advised in the other post, go to a set of scales and get a front axle, rear axle and total weight for your truck, loaded ready to camp. If you don't already have a 5th wheel hitch installed, you'll have to add about 200 lbs to the rear axle weight and to the total weight.

Payload by GVWR will be the truck's GVWR minus the actual total weight ready to camp. Payload by the RAWR will be the truck's RAWR minus the actual rear axle weight ready to camp. That will tell you what maximum pin weight your truck can carry.

That camper will probably be around 9000 lbs loaded, so with a pin weight of 20%, it should be around 1800 lbs when loaded.

Edit: With a loaded camper weight of around 9000 lbs, the truck weight needs to be 6000 lbs or less not to exceed it's GCWR of 16000 lbs. I'll bet that the truck weighs more than 6000 lbs.

I am sure you are aware that the towing numbers vary quite a bit by body style and bed length in addition to drivetrain.

So I will do a running edit of this post as I assemble the numbers so you can follow along. Bear with me as it can take some time (I am slow but steady).
Forgive me if I verify your numbers (always citing source material as a URL or attachment).

However before I get rolling I want to know if you are aware of a 5th wheel warning in the manufacturer's documentation regarding max tow rating for the 1500 series trucks?

From the 2008 Trailer Life Tow Rating tabulations page 17 and 18:
http://dcd96xmek71bc.cloudfront.net/...wGuide0801.pdf

"Manufacturerís note: Fifth-wheel kingpin weight should be 15-25 percent of trailer weight, up to 1,500 LB maximum."

"Manufacturerís note: Shortbed models are not designed or intended to tow fifth-wheel trailers."

So, assuming you have a long bed, this makes your 5th wheel max tow rating at 15% of trailer weight 10,000 pounds regardless of options or engine/rear combination per the manufacturer. At the "optimum for handling" ratio of 20% of camper weight, your maximum loaded camper that will keep the kingpin below 1500 pounds is 7500 pounds.

Since that is your empty weight (about) you will need to be pretty careful when you load it to watch your total weight and king pin weight ratio.

Dave, according to GM info the truck weighs 7,000 lbs, now I live in PA and I have a Class 2 weight rating sticker on my window, what does that mean, I have no Idea we have live in PA for just one year as of last month we lived in MD all of our lifes.

You need to check the palte on the door-frame for the truck's GVWR and RAWR. If the true weight is 7000 lbs, you'll most likely be about 1000 lbs over the trucks GCWR of 16000 lbs. You could change axle ratio which would increase the maxing tow and GCWR of the truck.

I think you'll be okay as far as pin weight, but the scaling exercise will well worth the $10.

Herk...the 1500HD is built on a 2500 series chassis, same thing as Dodge 1500 Megacab. They're not really 1/2 T trucks.

As far as towing a 5th wheel with a shortbed truck...I'm sure more than half the members on this forum are doing that now. Most new designs of the front cap may not even require a slider hitch with a 6.5' bed.

Don't shoot the messenger!

Just making sure the OP was aware of what Trailer Life was saying about the chevy's warning regarding 1500 series trucks and 5th wheels.

There are 2500HD drivers on the forum towing 15,000 pound 5th wheels too.
Just sayin'

If you ask for the numbers, I will get them. Folks ignore them all the time and most get away with it. Don't mean its right.

herk and Dave thanks for your help this is an eye openner and it is my first time with a 5th wheel, the bed is 6.5 ft. Now my truck does not have a 3/4 ton frame nor does it have a 1/2 ton frame, it has it's own frame as a HD 1/2ton truck. The brakes on it are the same size as the 3/4 ton trucks. Open Range Light 5th wheels they say can be towed by a truck bed as small as a 5.5 bed,????? the axle is a 4:10, where would I go from here as far as gear ratio?

Rockwood06...just to clear things up. The 1500HD I'm thinking about has 8 lug wheels and a GVWR of around 8800 lbs. Is this the same as yours?
