[AirsDream]

I'm considering an Airstream as a retirement travel / fishing lodge / sunset watching / get away "magic carpet." I've been window shopping for nearly a year and lurking here.

Most of the time I expect to travel solo. I plan to do a lot of "boondocking" as have some land and have friends with land available for "settin' a spell." Probable tv: an F250 diesel.

Questions:

1. Looks to me like a Safari 25 SE would be just the ticket for me - plenty larage for me solo and enough room for occasional guests, wife, etc. ... but to get largest tanks (big deal for boondocking), have to get the front bedroom, twin beds. Why is this?

2. Is it possible to get more than two batteries ... i.e. maybe 4?

3. Airstream - installed solar panels seem to have pretty puny outputs compared to models sold by BP, Kyocera, etc. ... any ideas why this would be?

Thanks for any help!
