In the end, does it "really" matter what other's are using, or doing, or whatever? As long as YOU are happy with your rig and it works for you, that's really ALL that matters, isn't it?
It's easy to get caught up in all the glitch and glitter of newer, bigger, and (supposedly) "better" things "out there." Advertisers would have you buying a new car every day if you could afford it. Folks who carry on about their campers, their style of campers, or whatever, especially who say, "this is the ONLY way to do it".... well ... are pretty narrow in their thoughts, in my opinion.
The only person I need to please is "me". The only person you have to please is "you". You can't live someone else's lifestyle.
Sounds like you've got a pretty decent 5er there. Nothing wrong with that. Until you have some kind of issues that become too big for you to handle or your life style changes drastically, I'd say your in pretty good shape.
One other thing you need to consider also, when it comes to full timing, I think, very few people just jump in and do it. Those who do have a lot to learn and over come. And if they've purchased the "mega camper", now they have an investment that's overwhelming.
Those who have graduated to full timing, because they've been the week-end warrior all their lives, they REALLY do know what they want (usually), or better ... they may know what they DON'T want in a camper. For those folks, they need to dream and ask question too. Still, it should never make you (or me) feel guilty, or get the "eye of envy" looking around.
I'm just saying, I suppose, if you are content with your camper, that's really all that matters. Take those comments with a grain of salt. They're dreaming the dream .... you're living the dream! Right?
