I think you may be underselling yourself a bit on the size. We had a 31' Class A gasser (Ford V10 on an F53 chassis) that we bought used as an entry level to see how we liked it in general. All in, we got a Thor with 17K miles, added auto levelers and backup camera and walked out of the dealer for $50K. It slept six if you counted the couch and the dining table. After our last trip with just the two of us a a small dog, we were fine until the grandkids (3 & 7) came to sleep over. Then there was barely room to move, believe it or not. Things get very crowded very quickly. Quicker than you would think, for sure. You say your boys are 8 and 10 now. How long do you plan to keep your RV? In 3 years, those boys will be 11 and 13 and fighting like cats and dogs. They are NOT going to want to be sharing a bunk. We just traded up to a Forest River Legacy 340SR 360RB. It's a 39' Class A diesel pusher with 1-1/2 baths that sleeps 8. Going down the road, the kids can sit in the back on the couch or at the dining room table and watch TV, play video games, etc. Brand new, we walked out the door for $173K plus taxes, etc. That's really not much more than you're talking about budget wise. In the process, we also looked at a Tiffin 32' diesel pusher, very nice coach with only 5,000 miles on it, for just over $110K. If you can afford the $150K budget, look for something like that. You mentioned the ride. Class A gas models are much smoother than the C's but are still like driving a boat. I couldn't believe the different when I first drove the diesel pusher; get your wife to test drive one of those in the mid-30' length after test driving the gasser and I don't think you'll have an issue selling her on the upgrade. Look and test drive, then decide for yourself, but give the pusher models a chance - think you'll really be surprised.
