Top RV manufacturers?

These are some of the best class Cs ever made. Might be hard to find a good used one, though, as people tend to hang on to them until...

Triple E and Coach House come to mind. If you’re considering used, take a look at the Bigfoot ( made in Canada). They are no longer producing motor homes, but those were good units. Our “used” Bigfoot has one of the highest fresh water capacities of the class c units(if that is important to you), and is well insulated for cold weather use. Of course insulation works “both ways”....easier to cool in “hot” climates. All of the above were/are “pretty pricey” units though.

Most of the “smaller” class c’s have the Ford chassis. Try for the E 450 chassis, gives a little more suspension for the heavy unit, and “generally” has a lower gear ratio rear differential.....which gives greater towing capacity (for toads or boats), and better hill climbing performance ( nice in mountainous terrain and some campgrounds)

for a C, check to see if it has leaked yet.

I think you will find condition is more important than the manufacturer.

A well maintained Thor in good condition is a better choice than a poorly maintained and beat up Winnebago.

Take your time and look at everything, when you find something you like, inspect it or have it inspected.
Use your search as a learning experience.

Enjoy your travels.
