Hi, Hopefully I will purchase my 1st RV sometime in May. I have a family member who is disabled and can't ride in a car sitting up for over an hour. We take a train (disability car)to travel and that was when I thought I'd get an RV. I was considering the Coachmen Freelander 21QB due to the length (23'6"). When speaking to sales person they want to put me in a 28ft or longer. I was wondering if anyone with experience could direct me as to what would be dependable even suggest another make or model? I want something that could sleep 4 adults. I would like a class B+ but can't find one to sleep 4 without being 28ft. The idea is to provide her a way to travel out of state to see family not to camp. We live in FL and travel to GA & NY so I need something with good mileage to warrant the RV over taking a train. I was told the 21QB comes in diesel but can't find one online. Thanks in advance for your suggestions/feedback.
