Chevy 2500LD CC/Sundance question(s)

Hi,
I'm new to the world of 5th wheels and still looking for "that" trailer. While looking at the Heartland site, I saw the new Sundance 5th wheels. It said they are 1/2 ton towable, but the weights don't look like it would work.
I have an 04 Chevy 2500LD 6.0 gas 3.73 axle GVW 8600/GCW 14,000.
My truck weighs 6450 w/ me, gas, toolbox(200lb), I figure close to 6900 with wife and kids and "stuff". That should give me around 1700lb for pin weight and 7100 for trailer. But in reading the spec for Sundance has:
2500RS 6948 dry
1296 pin
2700RL 7471 dry
1624 pin
2900RK 7333 dry
1549 pin

These are the ones I'm interested in. But, the only I could actually pull would be the 2500RS, correct? Or am I missing something...... like I said, I'm new at this and don't want to make the mistakes I've read about on other forums.
Are they really 1/2 ton towable? The GVWR sound to high for a 1500/150 TV. Can someone explain how they come up with this figure?

Thanks
Chuck

I realize that the factory people have other things to do...... but after a week, I thought someone would reply to this OR the email I sent. I hope the Customer Service is better!!

Sorry Chuck - but usually on "Truck" issues like that - I let the owners themselves put their two cents in. I'm very surprised that no one jumped on this one. Maybe it was because it was a new thread that they weren't used to being in.
Honestly, your truck should have NO Problems whatsoever pulling one of our Sundance 5th wheels.
My specs show the following:
2500RS -
GVWR: 11,175 Dry: 8,100 Pin: 1,624
2700RL -
GVWR: 11,175 Dry: 7,471 Pin: 1,624
2900RK -
GVWR: 11,685 Dry: 7,333 Pin: 1,549

A lot of owners are towing them with your truck set up without issue.

Hey Scott,

Thanks for answering. Are these the "published" weights or actual trailer weights after building?

Thanks

I'm not Scott but supposedly all of Heartlands weights are "as built" (a/c, awnings, etc). Our 3600RL actually came in 300lbs under weight. Just my 2 cents

These are the weights are given to me by our engineers - which weigh the coaches - which is what goes on our stickers and our literature.
