When purchasing your trailer from Bish’s RV, we offer you a lifetime of FREE yearly winterizations for your RV. This is our way of saying “Thank You” for purchasing your RV from one of our Bish’s RV locations.

During your annual RV winterization, we thoroughly inspect your RV, helping you keep the unit in top shape. We will check the roof and all your seals, wheel bearings, and winterize the RV & fill it with antifreeze (or blow out the lines). We will then recommend any repairs that will need to be done before the next camping season.

**Please make sure the grey and black tanks are empty before arriving for your RV winterization. 

Please be prepared to stay with your RV during the Free RV Winterizing days. The process could take up to 30 minutes depending on line length. All winterizations will be held on the dates below within the hours of 9 a.m. to 5 p.m. No appointment is necessary.  If you have any questions, please be sure to give our service departments a call for more information.
