Winter RV camping

????I am early currently in a Winnebago view 2009, definitely not made for four seasons but that has all changed I cannot believe manufactures do not try to protect water pipes in any part of the region to at least try to sell their products for a longer usage throughout the year this is what I’ve done to my Winnebago to make it for season. I have been in 6° weather Just crossing my fingers to make it through the first winter in the Sierras with the changes I’ve made??This is the link to my YouTube channel where I’ve tried to document my full-time adventures
