What do you want?
We wanted,
+ A bed you could exit without crawling over your spouse.
+ An easy to access pantry we could keep stocked all season.
+ Closet space so clothes could be hung all season.
+ A full bath.
+ Full time access for lunch, potty and stop and go overnights without unhooking.
+ A floor plan that would accommodate a rainy day inside.
We took a hard look at A-liners, particularly with the dormers. But we were able to buy a used TT with all the features we wanted for almost half the price.
We also acquired a lot of maintenance, 10 mpg, 250 to 300 mile days, 55 to 65 mph. wind buffets etc.
It came down to our need for convenience or all other factors.
Good luck
