SRW Truck Max length 5th Wheel

Am about to purchase a 3/4 ton diesel truck. We are going to upgrade our 5th wheel at the same time. Trying to figure out what the Max length I can safely tow. ALL kinds of stuff on line about DRW vs SRW towing weight. Not worried about that. Three or four companies now make light 10-11k 5th wheels, that are very long, with hitch weights of 1700lbs. The weight part is easily towable weight wise with a 2015 2500HD Duramax diesel. I'm not worried about weight on the single rear tires as the payload of the truck is 3000k+, the hitch weight is well within the safety range for SRW vs DRW. The rigs we like are 41-42 feet though. What I want to know is if anyone else has towed one of these new long/light 5th wheels with a SRW? Does the wind throw you around the highway? Looking for experience, not conjecture. Lot of money riding on our decision.
Thanks to everyone in advance.

After re-reading your post, if you are simply worried about a SRW 3/4 ton tow vehicle not having enough of a platform to pull a longer FW in windy conditions, then you don't have anything to worry about, generally speaking. Would a DRW provide a little bit of a broader platform? Of course it would.

That being said, there probably is not a 41-42 foot FW that once it is loaded could be towed with your 3/4 ton truck. You could probably hook it up, load it up, and take off down the road for miles and miles. However, if you took it across the scale and computed your numbers (while loaded) you would quickly realize that you were in trouble.

Being grossly overloaded is not all that uncommon when it comes to fivers, especially if it is your first one. You may even get away with it for a while, until that emergency stop doesn't work out so well, or that transmission burns up at 40,000 miles.
