For us, the convenience of a Class A and everything a rolling apartment offers while travelling down the road was the most critical. Your passengers can eat, sleep, use the restroom, watch TV, make meals, heck my wife has even taken a shower - all while going down the road. You have access to everything, electricity, all appliances, HVAC, beds, etc - all the time - not just while camped. It is such a joy to me to watch my family play a game of cards, eating meals, or relaxing on the bed or couch watching a movie - while travelling. No stops for restroom beaks (except for the driver). Traffic jams no longer bother me - I could sit in traffic all day. I mean, MH travel really is the most luxurious way to travel there is. It's a bit like having a private boat or jet. I've broken camp while the fam is still sleeping and been on the road for an hour before they get up and start their day. I think a fiver offers more space, but the inability to use any of the amenities while travelling was a deal breaker plus all the setup and breakdown. Not to mention the cost of a truck to pull it plus the fiver was more than a decent motorhome towing our existing car. And there is nothing like pulling into a campground in the pouring rain, knowing you don't have to do a thing until it stops. In a motorhome, wherever you go, there you are. There is very little setup to do and you are fully self contained without leaving the MH. *Disclaimer - not all the activities above while travelling are recommended. We do require seat belts while moving, and we are pretty safe in regards to what you can do and when. Didn't want the safety police flaming my post.
All that said, it really depends on what type of travelling and camping you do and what suits your needs.
