Buying RV that's been stored

I'm assuming you know how to check the date codes on the tires. They've been sitting a year or more depending on the veracity of the seller. Like any salesman, they tend to exaggerate. I don't even look at the tire except for the date code. Sitting for at least a year most likely took 2 years off their life span. Figure at least $500 per tire to replace. It will need an oil change and lube. Most likely you'll also want to flush and change the coolant. Inspect for rodent damage as that will present many electrical issues later on. Also check your engine belts for dry rot. The location of where it was stored is important also. A coach sitting in the hot desert sun of Arizona will have different issues than one that has been sitting in the cold and snow of Michigan. Take a paper and pen and go over the coach closely, then take it on a test drive. Remember rust is not a friend of your braking system so use caution there. On the test drive plan on at least 50 miles so there will be no surprises. Driving it around the block is worthless. See how it handles on the freeway...good luck...Dennis
