We appreciate our Nurses!
Yeah.. I think you will be welcomed here.. and will like, perhaps love the AS life. Depending upon one's neurosis, the space inside the AS may be restrictive... but, you can always 'go outside to change your mind'...
As said, there are RV's (SOB = Some Other Brand) which are specifically equipped for colder climes and weather. They are generally taller than AS... if it snows or water gets deep, the AS might not be as good a fit as the SOB... If you buy an SOB which has NO WOOD in the shell, that would minimize issues of floor rot like AS tend to have with poor maintenance.. or unresolved issues.
The AS has standard 'pink' insulation in the walls... but not thick enough because of distance between the outer and inner skins... also, the ribs of the AS will 'transmit' heat, in or out, because there is direct connection between those components.
Whether AS or SOB, they both depreciate. With more $ in the AS, you will 'lose' more... But, in 10-15 years, the AS, with proper maintenance, should still be in good shape!, still 'usable'... Our 1999 AS is still in service... and, yes, there have been a few 'issues'... but, with help here and good thinking, we have resolved all of them.
Good luck... and know we are always thankful for those who have answered the 'call' to be a Nurse... especially RN's...
