After doing a lot of research, we recently purchased a 2015 Itasca Navion 24M from Mike Thompson RV in Colton CA. We were attracted to it by: (1) the Mercedes Sprinter chassis with good fuel mileage, solid build quality, long service intervals, and so on. (2) The 24M floor plan was really attractive for our needs. We travel with 2 adults, a standard poodle, and a golden retriever. Having the considerable amount of open floor space, especially when the slide is out and the sofa bed is folded up makes moving around much easier than in any of the other Sprinter-based Class B or Class C RVs we looked at. Of course, the slide itself was a plus. (3) The rear bathroom was a major selling point. I'm a hefty guy and many RV toilets--even in 40 foot diesel pushers--lacked sufficient (how to put this delicately?) knee room when sitting. The 24M has plenty. Plus, the shower accommodates as well. (4) The short length makes driving the Navion a snap and (at least for now) eliminates the need for a toad. (5) The swiveling cab chairs and auxiliary table expand you living arrangement options a lot. (6) Good storage space, especially the rear closet in the bathroom. (7) Our RV came without the cab bed, which gives a nice open area that makes moving between the cab and coach easier.
We're storing the Navion at Benchmark RV in Sun Valley, CA. Very professional, very helpful, valet service. Not the warmest and fuzziest guys, but we like them a lot anyway.
We're just back from our first shakedown cruise to Flying Flags RV Resort in Buellton. We wanted someplace close to home in case anything went wrong and we'd always wanted to go to the Hitching Post (Sideways notwithstanding). We really liked both. My Yelp reviews are here.
Lessons learned: We did not do a sufficiently thorough inspection when we picked up the RV after buying it and missed several nagging minor problems. Latches not working quite right and so on. Hopefully they'll all be covered by the warranty. My next RV will get a much longer inspection.
Upon arrival at Flying Flags, we opted not to hook up the cable TV, city water, or sewer. This made it much easier the next day to unhook and drive over to Solvang. (Nice town but crowded and seriously kitschy).
Speaking of sewer, the black water and grey water tank meters proved ineffectual. When we left on Sunday, they still showed empty but when I dumped the tanks there was quite a lot of waste. As for the first time I ever dumped sewage, the less said the better.
The refrigerator took a long time to get cold, but when it did it ran fine. Is there a way to speed up the process other than maxing out the temperature control (I guess I should say, minimizing it)? Conversely, using both the electric and LP water heater elements meant we had hot water almost immediately. Once the water was hot, I turned off the LP element and had plenty of hot water the rest of the way.
I hooked my iPhone up to the TV using a lightening to HDMI adapter. Worked great at showing videos.
Our Navion has a sofa bed with foam mattresses instead of the old air mattress. As others have noted, there is a metal rod in the fold of the bed that is uncomfortable. Anticipating that, we bought 3-inch thick Wamsutta mattress pads and Travel Sack bags for both beds. They provided more than adequate cushioning. Storing them is a bit of a PITA, however. We still haven't found an ideal place for the full size pad that goes on the sofa bed. We're currently putting it back in the plastic container in which it came and stowing that in the shower during the day.
We averaged 15.5 MPG roundtrip with a mix of highway, backroad, and in-town driving. Total of about 250 miles, counting side trips. Still tracking down rattles, but the slide and the stove seem to be the main culprits. Still, there were a lot fewer rattles than I expected. Drives like a breeze. If you can drive a large SUV, this is no problem. Plenty of power for entering the highway and so on. Easy to park.
I'm not happy with the infotainment/GPS sat nav. It's too low in the dash, so you have to take your eyes off the road to use it. There is a huge amount of glare that makes it hard to read. It's a magnet for dust, fingerprints, and dog hair, which makes the readability issues even worse. The backup camera is pretty much useless. I am unable to figure out how to get voice navigation instructions without having the radio on.
