Oil change?
Problem: I changed the oil in my Holiday Rambler (Ford V10) last October with 5w20 Synthetic. Later I found my chassis owners manual that states I should use 5w30. Should I change it before heading...

Ford used a Technical Service Bulletin to change the oil recommendation to 5W20 with a particular Ford specification, for all of the modular engine series, all years, regardless of when it says on the filler cap or in the owner's manual. Using the Ford spec 5W20, the change interval is 5000 miles.
Ford has a semi-synthetic made for them, Ford branded, to meet the spec. It is also one of the least expensive oils that meet or exceed the spec, though many brands do.
I doubt if your oil will get much hotter running across Tennessee than it will any other place you go, engine temperature on that engine series is regulated to run fairly hot, for efficiency.
