My Itasca Suncruiser has a 7.5L 460 V8 Ford motor. I just returned from a 3 week trip to Pigeon Forge Tn. I'm in Ontario Canada. The outside temperature was obviously cool. It's winter. During my trip on some day's the outside temperature averaged about 45F, sometimes below freezing. My Temp gauge was always one notch above the C. Now Winnebago always has a rear heater and heat exchanger through the hot water heater. This all aids in keeping the motor cool especially on hot days. In the summer the gauge reads a notch below Normal. My dash heater was warm but not terrific. What do you think? Is this normal? Or is it the thermostat?
Thanks, as always...

Sounds like a thermostat. Better too cool than too hot, easier to correct.

Start by changing out the thermostat.
If that doesn't solve the problem you might want to try shielding your rad from some of the incoming air. You can do this with a grille blanket or even a piece of corrugated cardboard if you can insert it between the grill and the rad.

had a similar problem in my dodge cargo van... was never really warm and on freezing days i froze inside.
check radiator to see if it really hot after you warm up sufficiently (30 min)
can u measure temps? this where a inferred thermometer is handy... should be at discharge of hose going into radiator 170or more. if now replacement of thermostat is easy on a gas engine... $10 or so.\
a cheap temp fix would be to block off half or radiator with cardboard and tape. but you have to watch gauge so you dont over heat.
anyways after i changed thermostat... had lots of heat.
when u play in the sand .... you can get stuck

I agree, sounds like the thermostat. Typically they make them to fail open, so they don't cook your engine. Most folks would prefer bad fuel mileage and no heat to having to replace a head gasket and cylinder head.

I have a 1989 Ford 300 cu in engine in an E-150. When it was about 15 years old it seemed to run cooler. I changed the thermost, that fixed it.

Have you checked to coolant overflow reservoir? On many installations, the reservoir is mounted way out of sight (and access) around the left front corner of the chassis hidden behind some electrical panels. If you only fill the radiator to the top of the radiator cap, there's more cooling system that doesn't have coolant in it. On mine, it's the lack of cabin heat that is the most obvious sign of low coolant level. The engine seems to run about 1/4 scale low on the temp guage, too. Just an inexpensive thing to check before the tools come out...

Could also be the gauge or sender, but it never hurts to replace an old thermostat to start with.
