$159 for basic winterize.
$259 for winterize plus oil and tranny change and trailer inspection.

What is there on the ballast to winterize? Pull out the bags, blow out the lines if needed, I figure that's a pretty easy one to do yourself... I've heard of guys splashing a little RV antifreeze in their lines/tanks for good measure and thats only about $5 a gallon.

I'll stick with the shop guarantee for winterizing the engine! But seems like everything else is pretty easy to handle.
