Dually or srw

You need a new dealer. They are selling you a story since they likely have SRW in stock.

Biggest thing is they don't have a dually and they told me most dealers won't trade them, and I guess they have 20% certain models so if I want those I get even less picky on what truck I choose

In that case I too would go with a dually.

DRW. Easy decision. You've already stated the camper and gear will be 3,500. Your Jeep on a trailer at 6,000 pounds will likely have at least 600 pounds of tongue weight. That's 4,100 pounds without adding any truck accessories, passengers, pets, or gear to the truck. I assume you'll be adding some or all of those things which will put you over the rated payload of the SRW.
I've carried a 4,000 pound TC while pulling a 4,500 pound boat with both a SRW and a dually Chevy. The dually had way less bounce and sway. It just feels so much more stable and solid than the SRW.
A dually really isn't that much extra "hassle". I've been driving mine for 12 years. I use bank and restaurant drive thrus on a regular basis. Your camper is 8' wide so you aren't any wider when hauling the camper than you would be with it on a SRW anyway. Yes, you have to buy 6 tires instead of 4 but that only happens once every couple of years. Where I buy my tires they rotate them for free every 5,000 miles so I don't even have to do that.

Well you have to consider this carefully. Your maximum payload includes the weight of all your passengers, your hitch, your camper, and the tongue weight of your jeep trailer. I think just the tongue weight and the loaded camper weight will put you over with a SRW, and you still need about 600 more pounds for passengers and hitch at least, maybe more.

Plus you might overload the rear axle as it is based on the tires and their capacity. DRW sounds better.

I'm buying a new truck for work, so I'm pretty slim on options on what truck to buy since it has to match the fleet. So I'm looking at a crew cab long box 2017 gmc, either the Denali or slt depending what they can find me.. I'm really suprised to see the the srw is rated at 4188 with the duramax engine! The dually bring you up to 5410.

Now my camper is a 04 okanagan 811sl which according to online is around 2600lbs dry. I figure with all our stuff and water we're around 3500. Now I'll be towing my seadoos behind use at around 2200 pounds and sometimes my Jeep, which will proably be 6000 pounds with the trailer. Is the drw going to be worth it for the extra hassle?

I don't think so, but the cost of the drw versus the srw is so minimal, why not? You don't come close to even needing it really, but again, cost to upgrade is so small, why not :)

Are you referring to pin weights?
