I owned a 2006 Ventana 3936. We bought it new from the Midway (Grand Rapids, MI) dealer lot in Sept 2006. We loved it and the dealer. I only had to take it back to the dealer once - for a 5 year check up and to get the Norco frig recall done.
As an entry level class A diesel RV, it had many std features that other brands only included on their higher level units. We had good service out of our CAT engine and Frieghtliner chassis. Newmar builds a solid, quality product.
I know that in 2008 the Ventana line had evolved to include more options, including changing chassis and engine MFG - both of which have a strong positive reputation.
We just traded and ordered a 2013 Dutch Star. We liked the Ventana, but now have children living on both coasts, so felt it was the right time to upgrade the chassis and engine for the longer cross US trips we plan to make each year.
