Thanks Rednax, Brian and the rest of you, All sound advice.
I do have a lot of towing experience with different types of vehicles.
Our last Motor home, a Freightliner Columbia / Showhauler MOHO conversion used to tow a 32 ft. stacker trailer for Drag racing. Safe it was, but it was overkill.
It's gone now to a good friend but, It was built with the thought in mind of safer towing, in case of an unfortunate accident.
Its was much safer than the Winnebago Journey towing a 30ft tri-axle trailer I had prior, strictly from a collision standpoint, Otherwise it was a great coach that did quite well.
That's why I'm discussing the 1500
Suburban as a TV with all of you.
Today I had the pleasure of talking with a very knowledgeable sales person at a AS dealer. After a lot of great discussion, I understood that a 1500 Suburban is a good choice for towing a Flying cloud (because of weight) 25 FB or 27 FB and a P.P. hitch. this combo has been used by many of their customers.
When all was said and done, I felt very comfortable with their vast knowledge of the AS wet weights and the 1500 Suburban for a TV.
I felt that after our conversation, all I had left to do was decide on the 25 or 27 Flying cloud or International. I lean towards the 27.
