We've had tents, pop-ups, TT, Class C & Class A. The only thing we have not owned is a 5'er. I love the roominess a Class A offers, but if it were just me making the RV decision, I'd have a Class C because I'm more comfortable driving a C versus an A.
If I could go back in time, I wish there was a vaccination against "1 Foot-itis". What is that? That's when, once you've settled on and bought an RV, after you start using it you start dreaming of a longer RV with more slides and toys. We have owned 5 class A's, starting with a 26' Southwind, going all the way up to a 45' Travel Supreme bus, and have come back down to a 32' Itasca Meridian. I get sick when I think of all the $$$ I've lost trading up & then trading back down again.
You should evaluate how much time you will actually be using your RV and look at a lot of floor-plans. When you narrow down the playing field, spend some time in some of your favorite ones and really look for the negative features - such as - if there's enough walking space around the bed - how big is the shower - if the kitchen really accommodates your cooking needs - does it offer enough storage...in other words, if you were forced to live in it, could you - or is it adequate enough for week-end getaway's and vacation time. This is a very personal decision and one you must force yourself into taking your time to find the right fit for your needs and your pocketbook.
Also - BOTH of you need to feel comfortable driving the RV. I can't begin to stress how important that is.
