You should buy the one you like best. Does the floor plan work and which do you like to drive the best. Tiffin and Winny if you get them equally equipped should be about the same price. In my humble opinion Winnebago is less controversial. By that I mean Winnebago mostly good reviews on this site. Tiffin seems to have lots of haters and lovers. So I guess it is a more polarizing brand. The RVCG /RV Consumer Group rates pretty much every model of motorhome made in the USA. Go to their web site and see which they like the best. If nothing else the RVCG information is a quick way to see what the CCC is, towing capacity, and so on.
