I guess what I'm asking is it to much trailer for that truck?
I agree with Rjhuser, you should go to a CAT scale and get your setup weighted.
This way you know the true weight of everything to see where you stand with TV GCWR, TV GVWR, TV Rear Axle GAWR, & TT GVWR.
You should be able to figure out your pin weight if you do 2 weightings.
(1) Unit hooked up with TV Front Axle; TV Rear Axle, & TT Axles each on a separate scale.
(2) Weight only the TV with TV Front Axle and TV Rear Axle on separate scales.
Then Loaded TV Rear Axle - Unloaded TV Rear Axle will give you your pin weight.
And the calculated pin weight + the TT Axle weight will give you the total weight of your trailer to compare against its GVWR.
I have a similar TV (just not w/ the Denali package) towing a 2015 Eagle Premier 361 REQS (see sig
) and I'm very close to my TV GVWR & TV Rear Axle GAWR. So we need to review & remove some of the stuff we pack that we really don't need.
You definitely would have more buffer with regard to load capacity with a dually. Plus from what others have said and what I've read a dually will give you much better stability if you encounter windy conditions while driving, particularly any side winds.
To answer your question if your truck is enough, the weights will tell you that.
I also agree with what dalengail said, you're probably good for now until you're ready to upgrade your TV to a dually.
IMO, there's no need to go out and upgrade your truck to a dually immediately, unless you're looking for an excuse to do that.
Good luck and hope this helps.
