Hello. New to the forum, but I have been using the search and read through a number of threads, but I have a slightly different question about towing.

I am thinking about upgrading to a slightly larger travel trailer. I've been towing a trailer with a dry weight of 4500#s and a hitch weight of 550#s. I estimate the actual loaded weight of the camper to be around 5500#s when towing (if the water tank is full).

I have a 2015 Suburban with the max trailering package. Online indicates it has a maximum towing ability of 8000#s. Of course, it never feels like the current travel trailer is hooked up - even in the mountains. The Suburban handles it with no problems.

I am looking at a travel trailer with a dry weight of 6400#s and a hitch weight of 700#s. If we assume a similar packed weight of 1000#s - bringing the camper weight to about 7500#s, will the Suburban still handle pulling this thing in the mountains? Obviously, it will be a bigger strain being 2000#s heavier than the current trailer, but is this too close to the maximum for the vehicle?

What engine, trans, diff ratio do you have?

I am pretty sure all of the 2015 Suburbans have the EcoTec3 5.3L V-8 engine.
Transmission is the same across the model year as well - Hydra-Matic 6L80 6-speed.
This one has the 3.42 final drive ratio because of the max trailering package.

Its will do it but it will be working very hard. This is severe service so adjust your maintenance schedule accordingly.
