We really like our '11 G'town a lot and had looked at several before settling on it. In fact, we started out looking at Class Cs but one salesman drug us into a Class A and that was the end of the C search. We liked the floor space in the living area. Not that the furkids lay in the floor (they're usually on the couch) but on the rare occasions that they are on the floor, it gives us room to move around them. There is quite a bit of storage inside as well as a good sized basement with access on both sides and several other storage compartments on the outside.
One that we looked at was a Thor ACE. It had a LOT of very nice features but the killer in our opinion was the floor plan. Since the then, they've redesigned them and improved the floor plan. You might want to take a look at them too. They are sort of a hybrid between an A & C and have a bed over the cab area. To do that they had to shrink the windshield some. It's still bigger than a C (I think) but not as big as the Class A. The ACE is a sharp looking MH.
We've had one problem with our G'town which was covered under warranty. A seal in the hydraulic reservoir for the jacks blew and we spewed hydraulic fluid all over I-40 in Texas. Fortunately, the jacks stayed up and we were able to get it repaired at a dealer the next day. We've camped 2 seasons in it although due to family obligations, not as much this year as we wanted to. We don't baby it but we do take care of it and IMO, it's holding up well. There have been a few "fit & finish" issues that a bit of glue or a screw has fixed. Actually, it's surprising that there aren't more things that work loose and need attention considering the amount of movement there is. Imagine driving your house down the road with all the vibrations, potholes and & uneven pavement.
I haven't looked at the new G'town floor plans but you might want to take a look at the bed. Ours is accessible on the left side and foot. The right side has a handy shelf thingy that runs the length of the bed. The left side does not. I don't know how long it is but at 6'4", your feet might dangle!
The shower isn't huge but bigger than many we looked at. We've both taken showers in it and haven't bruised our elbows. The major gripe I have is where the goofy water filter is. It's on the floor under the left corner of the bed at the foot. You've got to lay on your belly, manuever into a position where you can reach the filter which is to the left of the door! I'd like to talk to the genius that thought that was a good place for it.
We've gone as long as 5 days w/o dumping but that's with taking showers in the shower house and being conservative with water usage. You really need to use quite a bit of water in the black tank though so it's hard to reduce it much. We've camped for up to 3 days on our water tank with no issues. We could go longer, it's just that that's the way the timing worked out. The generator is LOUD so not conducive to happy neighbors. We're looking at a muffler and other noise reducing options.
We towed a Jeep over the Rockies from Denver to Moab and while we didn't set any speed records, we did not have to get out & push. Wind will shove you around & passing semis sometimes cause a sway. After getting sucked toward and then blown away from semis for a year, we figured out to adjust the air pressure in the tires and that helped a whole lot.
The floor gets really hot from the engine which is between the front seats. We added insulation to the inside of the doghouse & under the floor board which helped the heat factor a lot. The front windshield is great for viewing but the sun shining in makes it an oven pretty quickly. That's one reason we don't drive too late in the day when we're going west! The little fans that are by the windshield are noisy little beasts and aren't all that effective. The radio is maddening. Almost impossible to use. Good thing we have a Sirius subscription. The fridge is good sized and has worked well. The microwave isn't huge but isn't one of those itty bitty things either. I've not used the stove!! LOL! Well, it's where I store taters & onions.
There is storage under the dinnette benches. The closets in the bedroom are plenty big.
Any unit you get is going to have things you really really like and a few things that you don't like and you learn to adapt. I'll do my best to answer any questions you have about the G'town. For us, the things we like about it far outweigh the few negative things.
