Firstly, thanks for all the feedback. Did not expect to see so many replies.
I see many suggest a shorter unit rather than 30’ plus. We got so used to a large 5th wheel that I must say I like a bit of room, so we have to go and find the right balance for us.
I had a class C E450 (2003) before, one down side was the small leg space for the passenger. Ours had the dinette bench right behind the passenger seat, so one could not move back or recline much.
I noticed the comments about the Chevy having more leg room, I will check that out.
I also noted a few Chevy Seneca units, the bigger Chevy chassis, seems to have more space up front and looks wider? Any comments on that particular chassis?
