[OhScottyOh]

Have recieve much valuable advice from learned folk on this site, thanks to you all. At this time I would like to hear from some with similar TV experince.
My current TV is 03 4Runner 4x4 4L V6, Limited, Trailer Towing Package, AC, AT, 640 lbs tongue rate, CGVWR 11000 lbs. gross trailer weight 6400 lbs cap. and will be mounting HAHA with new Airstream.
My current tailer is a Starcraft RT 10 pop-up, when loaded weights 2500 to 3000 lbs, and using just the weight carring hitch. My driving style when towing has been 55-60 but have been known to exceed the limit a time or two, the little trailer is like it not even there. I tend to stay off Interstate when possible, been over lots of Colorado passes on and off road with trailer, Engineer, Cottonwood, Independance, Rabbit Ears, Monarch, just to name a few.
It is time for a change and a lot more class, so Airstream is the answer. I am considering a 25 Safari SE FB. Spec out at under 5900 lbs with freshwater and propane and equipt as I want.
Yes I am pushing it a bit but would like to hear from others who may be doing the same or have done the same.
Oh yea, I will probable keep the RT for places that the AS won't go.
Thanks again for all your help and advice.
