We did the same thing, moved from tents to a tiny tent on wheel (1966 raven apache) then looked to educate ourselves -and are still learning.
No salesman was capable of truly explaining the difference between brands or identifying what you didn't get with the entry level models - I don't think any of these guys camp or they'd have a clue.
I was most concerned with construction quality - will it hold up? I'm happy with what we got, but learned a bit on what's missing with entry level units. For how much we'll use it that's fine, but if I were full timing i'd be better off with a high end model I think.
What we're missing...light switches on teh walls (kids can't reach the ceiling fixtures), hot water heater is manual start only, 'missing' cabinet access doors/drawers (got blank off plates instead). Minor things, but they are things you 'use' or notice everyday.
We went shopping to get a ~23' hybrid and ended up with our 28' bunkhouse - we're glad we did but it did entail buying a bigger TV than intended and that meant buying an older/ more well used one to keep within our budget.
Enjoy your new 'home'!
