2002 Oldsmobile Bravado as TV

Hi,
Tomorrow I will be picking up my first travel trailer a 2002 TM 3023.
I have an 2002 Oldsmobile Bravado (with air suspension). If anybody has experiance towing with the Bravado I would appreciate their feedback on how good or bad the Bravado is as a towing vehicle, and if any towing equipment was needed.

In May we are planning to make a Trip from Galveston, Texas to Denver, I am concerned about the Mountain passes and if the Bravado towing the TM 3023 will have sufficient power to make it to the top!

This is our first travel trailer, and our first trip is to Baycliff, Texas, overlooking Galveston Bay (about 5 miles from the house) we are playing it safe!

Any guidance you can give me will be very much appreciated.

Many thanks

Brgds
