Can I winterize my Pop-up camper myself?

Drain the tank and if you have a small aie compressor blow out the lines is all you should need. If not add a gallon of antifreeze turn on pump ans pump till you get pink stuff out. Be sure to add some pink stuff to the sink drain. Ans put it away. Just make sure there is nothing that can freeze in it and your good to go. Reverse the operation in the spring. Being sure to flush with plenty of bleach water
