"I would highly recommend you look at the Palazzo RV Class A Diesel pusher. I got one for my in-laws"
Sorry I just could not resist.
Most of the responses have been from folks with large C's, ours is a Nexus Phantom 23P that comes in at 24' and change. Our 26" TV is mounted at the foot of the cab over bunk on a mount that swivels/angles out. It can be viewed from the cab over bunk, the large booth dinette or the full queen in the rear left corner. We usually use the cab over bunk as a TV lounge or for reading/napping as watching TV looking up is a pain in the neck.
Our storage bay is large and holds chairs, back up Honda 2000, firewood, tools etc. Have yet to come close to filling it. Our center galley works well, we have a flip up counter that adds additional counter space and the large dining booth table is directly behind me when cooking. Try for a real oven if you do much cooking, our 3 burner stove includes a conventional oven and we have a huge microwave above with the standard range hood.
The dash AC on our 2012 puts out more than enough cold air to keep the entire coach quite comfortable while driving. When we settle in for the night the 13,500 BTU roof air turns the rig into a meat locker in about 10 minutes. We also have a 35,000 BTU propane furnace and heated tanks that enables us to deal with cold temps without a problem.
The interior storage is unbelievable, after 6,000+ miles in the last three months we have yet to use about 40% of whats available. We have the E-350 Chassis with the 6.8L V-10 and it is a beast. Married to the 5 speed tranny with full tow/haul mode it eats up the mountains without even breathing hard and still gives us an average of 10 mpg (I cruise at 60). The ride is smooth and stable and the 55 gallon fuel tank gives me 500 miles of range with a 50 mile cushion. Our CCC is 3,368# with a GVWR of 12,500. Weighed the rig at a scale in Oregon with one third full grey, black, fresh and fuel tanks, we came in at 10,050#.
We have a Class IV Reese hitch and are rated to tow up to 5,000# with a GCWR of 18,000#. Nice to have the V-10 beast in a relatively small Class C. At just under 25' we can go to any shopping center, down any road or get into any site we encounter. Doubt we will ever have a toad, just no need.
For the record the Nexus might just be the best built C in America. One piece solid fiberglass roof and end caps, framed in steel (not aluminum), heated tanks, Amish cabinetry. the fit and finish are off the charts and they come very well equipped for around $60,000. For us, with just 2 and the pooch, I can't imagine ever wanting, much less needing, anything bigger. As always... Opinions and YMMV.
