How long is too long...

This is a question to which the answer is largely subjective, but I am curious about your experiences. We have been discussing upgrading to a Class A when retirement comes along, but with the price of fuel, rising costs for maintenance, and industry upheaval it is starting to make us nervous.

So...for just how long have you comfortably lived out of your TM without really starting to get claustrophobic/bonkers/uncomfortable? Assume you usually have full hookups or E&W, and stay in one place 2 weeks at the longest.

What tricks have you used to maximize storgage and otherwise make the most of your TM (we have a 3124KS)? I am not against taking a night in a nicer motel every week or two just to decompress.
