We do appreciate our 2010 Chevy/RoadTrek 190, upgrading to a Class A or Class C does increase the living space, does increase the storage, and more room.
When at a campground most folks spend time outside of their unit, in a Class A many folks spend the time inside, rain or shine in the front seats looking out.
We have no problem at night in the RT 190, I enjoy being up front on my computer or watching a movie on my computer, and Rose is in the back watching TV or a movie, or on her Kindle Fire HD reading.
Of course if it is raining we are able to go shopping, go to a restaurant, move around a area freely in our Class B, take the dogs out to do their business, park freely in a parking lot or at a meter parking space.
With a Class B whether it be a RoadTrek 190 or 210, PleasureWay Lexor or Excell or any other Class B's you don't have to tour a vehicle behind you unless you want to, you are able to go sightseeing with a B. The nice part about a B you have your own bathroom with you, your own kitchen. You have your home away from home with you.
If I were "classbwannab" if possible I would go to a dealership that sells RoadTreks or a dealership that has RoadTreks and other Class B manufactures, check them out drive them on the highway. Seeing that there is a toss up between a RoadTrek 190 or 210 take a test drive on the highway with a 190 and a 210, see how each handles, then you will be able to decide as to which one you prefer.
