OP
Above are 3 Senior Members the best advise for you checking your profile is from CoolMom42....
Go to several RV shows, leave you check book, credit cards and money at home. Just look... Set on the chairs, dinette, lay in the beds and stand in the showers, cook at the stoves.... see what fits you... there are no perfect RV's. Even the Million Dollar ones made to order. So look, and don't believe the salesman... once you find something go on the internet and research. Then fin the TRUCK not SUV, long wheelbase truck that will pull it up the mountains and down the valleys.
For me it would be a 40' DeLux 5th Wheel and a 5ton truck. but then again that would be mine not your.
