We have 2014 Itasca Navion IQ 24V (actually 25.5 feet long). On 3500 Chassis. Winnabego View is exactly the same. Winnabego has dropped the Itasca name this year. All navion/View configurations can have the cab bunk or not, that change made last year. Quality of the Navion/View is fantastic, Liesure travel is also great. Both one piece fiberglass roof, insulation on Leisure tvl is a bit thicker floor is built on the frame about 6 inches lower than Navion/View which is built on a 6 inch Aluminum box frame.. Liesure Tvl does not have twin bed model or G. A friend of mine has owned Navion and Prisim he is back to the Navion G he believes the quality of the Navion is better. Liesure tvl has a smaller dealer network. I am not a fan of the Murfybed, it is in the main living space, both people must go to bed at the same time.
We are getting 16.5 per miles per gallon. Quiet Diesel engine on all Mecedes. Good power, road noise is alittle more than I like. We are looking to do some sound proofing mods in rear wheel area.
Slide on driver side with hide abed, sleeps one adult or two children if they like each other.
Twin bed shower is slightly larger on the V model than the G. The water heater and water pump are easier to access thru the rear compartment than the G for maint. and winterizing.
We like Twin bed because of the two separate living spaces. Wife goes to bed hours before I do, she has crafts and we don't have to reconfigure (make the beds) to sleep or drive. Plenty of storage full extension drawers under each bed plus over head storage. Large storage in all but one external compartments. The storage under the slide is where we put things we don't need often because when the slide is out it is harder to access. Only down side in the entire rig, to empty the gray tank water is pumped to the dump side, it works well but I prefer gravity dump.
If price is the issue look at 2011 thru 2014. I have seen pricing anywhere from $57k to $85k for a low mileage unit.
Hope this helps
