Full timers have a tendency to run at trailers GVWR
What is the payload of your XXXX Chevy 2500 Durmax?
Payload----what is actually available after truck is loaded ready to camp (passengers/passengers stuff in cab/stuff in bed)
Trucks GVWR minus trucks actual ready to camp weight----payload available
(Taking in to consideration trucks available rear axle weight and rear tires MAX Load Rating)
The tow rating may be 15K but in the real world you will run out of payload capacity and bump up against truck GVWR long before you get to tow rating.
Sure there are quite a few 2500s towing large/heavy 5vrs with air bags, suspension products etc. but they are running over their ratings.
Otherwise they wouldn't need the air bags, suspension products etc.
Take the time to get your real weights and then do the math.
At least then you will be making an informed decision......right/wrong/indifferent but at least informed
When you figure out what your real payload capacity is then look at a trailers GVWR and take 20% of that figure----that will give you a close idea of what that trailers pin weight will be when loaded.
Is that pin weight within your available payload capacity???
My 14K 5vr puts me right at ratings on my 3500 SWR
