We gave the A-Liners a very hard look but decided.
* We wanted a bed we could exit without crawling over your partner.
* We wanted closet space so we did not have to live out of a suitcase in the TV.
* We wanted a full size bathroom, sink vanity and towel storage.
* We wanted a pantry for food, dishes, crock pot and coffee maker.
* We wanted room to move around inside on rainy days.
* The TV and Microwave were a nice touch also.
We were fortunate, storage is not a problem, we found a used 25 ft. TT with slide out for less than an A-liner. We are sightseers so we are rarely in one spot for more than a day or so.
Down side, more maintainance, we needed a bigger TV, 10 mpg and you are pulling a barn down the road.
