Greetings from the Florida Panhandle
Welcome to the Forums. We're glad to have you with us.
As to your dilemma, we have had two 25FB's and one 23FB. We are somewhat experienced Airstreamers. We have camped in our Airstreams for almost 1,800 nights, and have towed them over 160,000 miles over the last eleven years.
We started with a 2005 Safari 25FB. We really enjoyed this floor plan, and found it very livable for as long as 100 consecutive nights of camping all over the country. After about eight years, we decided to downsize. We traded for a 2012 Flying Cloud 23FB. We used it for almost a year. We spent over 150 nights in it, and towed it 15,000 miles. This floor plan did not work well for us. We decided to go back to a 25FB. In October, 2014, we traded for a 2015 Flying Cloud 25FB. Since then we have logged almost 30,000 miles and have camped almost 300 nights in her. Needless to say, we prefer the 25FB. Choice of floor plan is an extremely personal decision.
Our best suggestion is to spend some real time sitting in the different models that you are considering. Get a good feel for the flow. Also keep in mind that the 25FB is six inches wider that the 23FB.
As to your tow vehicle situation, the Canyon may be marginal for towing a six or seven thousand pound trailer. The best way to find out is to try it out, especially since you already have the Canyon.
Also remember that it is usually a bad idea to buy an Airstream to accommodate a tow vehicle. An insufficient tow vehicle is the most common reason that an Airstream becomes a very expensive piece of yard art.
