Hello KeithCheri ...or Keith & Cheri -- welcome to the forums!
You are getting some good routing and tourism advice, but let's get back to your basic question. The Tahoe may not be the best long-term tow vehicle for a 25' Classic. Current day Classics show a hitch weight of empty trailer w/o options to be 870#
. LP in your tanks, weight distribution gear, and any
reasonable personal gear on the trailer will unavoidably push the hitch or tongue weight up to at least 1000#! That being said, you may be able to do the trip and I hope your Airstream dreams are only sunny.
I've been through this in detail recently on the GMC badgemates at this thread
. The Tahoe LT looks to have exactly the same numbers as the straight Yukon, as seen on this line:
The Yukon has [load capacity] numbers of 1522 & 1590 for two different models.
If your hitch weight is 1000# (and weighing it is the only way to establish the actual number), the Tahoe's load capacity dictates that the remaining load (passengers, etc) in the TV can be either 522# or 590#. Can you do that? [Look at the Capacities/Payload
area for the Tahoe LT
. The Trailering/Max. Trailer Weight
is secondary. First and foremost you can not expect to safely drive an overloaded tow vehicle.]
I will accept any corrections to my remote figuring and have not owned the TV in question. Ultimately you would be advised to re-read & understand the towing section in your Tahoe owners manual. Related info is on the Airstream FAQ page mentioned in the Yukon thread. Really though -- fall in love with your Airstream and adventure! In my opinion it would be prudent to make long term plans to upgrade your tow vehicle.
