I have a '12 stick shift Fit that I drive as my daily driver, with somewhere around 135K miles on it now. I have not pulled it behind my motorhome, however.
I'm quite fond of the car, I must say; it's been extremely reliable and trouble-free, and is relatively fun to drive for a cheap little car, and has a very flexible iterior arrangement. The gearing is a bit strange, with the gears rather lower than I would like (I wish I had a gear above fifth gear sometimes, or more to the point a different final drive ratio). The new ones with the six speed transmissions have the same basic overall span of ratios, just with the gears closer together, for reasons known only to Honda.
The Fit does get quite decent gas mileage. It is not a quiet or luxerious car inside, which is hardly surprising. I do think it's a bit ugly, but at least it's ugly in a kind of cute way. Adjusting the valves or changing the spark plugs is a bit of an ordeal, requiring disassembling a surprising amount of stuff to get at the top of the engine, but it's not like either one needs to be done super frequently. Other maintenance seems to be pretty straightforward.
