We started with tiny (Toyota) ClassC about 30 years ago and when family was growing - so was RV. Last sold was Prevost conversion.
Now we retired, sold the house and are "fulltiming" in truck camper.
I bought the camper 4 years age, still having bus at the time as with sons out of the house, I could keep the camper at home, while bus had to be in storage.
Anyway, lot of choices and there is no "one shoe fits all".
We are happy with our long camper with single slide. It has all we (and 3 small dogs) need.
But just yesterday neighbor invited DW to her trailer.
3 slides, center kitchen island, electric fireplace - RV sure went long way from our Toyota.
Long ClassA is the most comfortable choice, but also the most expensive and fixing those things on the road is not going to be easy.
Having truck already - for me luxury camper was straight-forward choice.
VERY economical, I can drive and park it everywhere and in emergency I am rolling in 1 minute. Not that you should buy RV with emergency in mind, as those things normally never happen.
