I really think you should consider all the pros and cons before settling on a particular type of RV.
I know you seem to be settled on a class B by looking at the pros but I want to point out a couple of cons to living and traveling in a motor home.
First, since you are buying used you must consider the possibilities of breakdowns and repairs. If your motor home experiences an serious mechanical issue that requires it to be in the shop for an extended period of time, where will you stay while it is being repaired? Motels and hotels can get expensive fast.
Second, living for extended period in a motor home pretty much requires you to purchase and tow a smaller vehicle behind it. You don’t want to unhook sewer, water, and power, and stow stabilizing jacks every time you go to the grocery store. Also in many of areas of the US there are great national parks with back country roads that are too narrow or steep to be accessed with a motor home, once again requiring a smaller vehicle.
If you are set on a class B, great, but I just wanted to point out the negatives before you made the jump. And in case you are wondering, my wife and I full time in a TT towed by a Nissan Titan, so I am a little biased.
Below is a photo of our rig.
