IMO they are too small inside and have almost no storage. It would be hard to take a month long trip with a 25-28'. For 60-70,000 you get this,

The AF would be 244.00 a mth for 120 mths for a total of 35,000 paid over the 12 years. APR on both was 3.99%. I'm sure there are variables in all this. But how much will the AS be worth after 15 yrs. 20,000 in interest as opposed to 8,000 for the AF I'll take the more user freindly cheaper rig. Not sure it's worth the extra 200.00 a month. Basicaly you could buy 2 AF's for one AS.
I used an AF because they areone of the best bulit 4 season units out there.
