This is a question only the OP can answer. There are a wide range of rigs, from a Roadtrek 170 Versatile, to a 45 foot "A".
As one moves up in length, one sacrifices things. At 20-22 feet, the ability to take up one parking space is lost.
Here is an odd thing: I was looking at Thor Freedom Elites (which is a Camping World house brand.) Even the 22 foot model now uses a Ford F-450 chassis and has an 8000 pound tow rating.
The Thor RUVs are reasonably priced. However, (and I don't intend this to be bashing any brand, but just pointing out you get what you pay for), the $120k spent on a View is going to net you shiny veneers, and higher end trim levels.
Here is what I did to solve this problem. I went and looked at the Thor class "A"s. I went and looked at the Views/Navions. I looked at the class "B" vans, with most Sprinter models having a 5000 pound tow rating. Try sitting on the bed, sitting on the toilet, open the fridge, sit in the driver's seat and adjust it. Visualize what you will be doing in a rig.
Motorhomes are expensive... I say do one's homework.
