You don't mention what your tow vehicle is. We tow our Casita
17 with a 2000 Chevy Blazer V6 2wd.
We are 2 retirees and find the Casita
has everything we need. We no longer have any pets.
Before the Casita
we had a 20'stick-built. One of the problems with "small" stick-builts is that the manufacturers are focused on the large units and the designing and testing of the small ones gets short changed. I wish we had bought the Casita years earlier.
With the stick we got 10 mpg, with the Casita we get 16 mpg. More money for travel.
I pull the Casita through places where I wouldn't try to go with the sticky.
Short trailers are trickier to back than long ones, but it has nothing to do with tandem or single axle
. Tandem axles don't like to make tight turns when backing.
When a tire blows on a tandem axle
the other tire on that side is immediately grossly overloaded. I once had 3 blowouts in 2 days on a 1 year old tandem axle
