Good Sam Community

I suggest you ask this question on one of the Facebook groups. Those groups are very active and you will probably get lots of opinions  You could try: https://www.facebook.com/groups/ClassBCamperVans/ and/or https://www.facebook.com/groups/Roadtrek...

A lot of the Roadtreks have side showers. Look on their website.The WBO Travatos have showers either across the back or in the back corner.

Diesel can be a little harder to find than gas is my understanding. The same with Merc mechanics vs Chevy/Dodge/Ford.

I think Roadtrek is just bringing out a shorter version of the ProMaster van called the Zion SRT which is 19'7" long. Not sure if that counts as a van for you though...

What do you have against the ProMaster chassis?  Just wondering...
