We are first time RV owners this year and just had our camper winterized. This is a rookie question.
So I realized all the drain tubes on the bottom were left open when I dropped off the camper to be winterized. I called to let them know because I thought that mattered. They had me pick it up and they are all still open. Does that not affect anything? I thought the antifreeze would just drain out if those were open. Teach this new guy some info, please! Much appreciated.
We have a Keystone Bullet 2200BH.
They charged for antifreeze so they didn’t just push air through the lines.
