Thanks for the feed back. Appreciate your response. All of what you describe is waht I was thinking about. Thanks for confirming it. We have a 08 Tahoe with the same drive train and it sounds like a perfect match.
Now all we need to do is sell our Komfort trailer

I apologize for not answering your inquiry way back last July. I am a novice at this forums and private message thing. I never noticed your message until tonight.

We have never experienced any trouble with towing. We tow the trailer with a 2007 1/2 ton GMC with at 5.3 liter V8 engine and a 3.73 rear axle ratio. We have towed it up and down some extreme mountain slopes. Many long stretches of 7% and 8% slope and one 4 or 5 mile long at 13%.

We have a Reese Dual Cam hitch and we have never experienced any sway, either with strong cross winds or when being passed by semi rigs. I consider it the best hitch for the money. We private messaged Andy at Inland RV and told him what truck we were buying and what trailer we were ordering and he told us to buy the 600# bars and he was absolutely right. The technician who installed the hitch said it was a perfect combination.

We live in Michigan and have taken many trips in the the state and have taken a 4,000 mile trip to the northern Rockies and a 6,000 mile trip to New Mexico, Arizona and Utah and have never had any problems with the trailer and tow package.

We chose the 20 foot trailer because it had the best galley set up of any Airstream including the larger models, it has a great deal of storage space and also we like the front bed. We chose the small size trailer to better get into out of the way places.

The single axle trailer is easier to over steer when you are backing into a campsite. But with experience I am learning to make smaller steering adjustments to avoid the over steering problem.

I have a question if you don't mind. We are thinking of a 20 ft like yours but I've been reading about how it tows. People mention something about hitch pounding being a single axle trailer. Can you tell me what your experience is towing? It is a beautiful trailer by the way.
Thanks
