For those of you trying to cozy up your RV home during this cold spell, the bubble wrap idea I referred to in an earlier post works quite well. Another benefit I forgot to mention last time is a lack of condensation. One reader asked how I attached it to the windows and my answer is with a small amount of packing tape. It is also held in place quite well with the day/night shades pulled down over top of the bubble wrap.
Wal-Mart has bubble wrap for $5.00 and if you do not want to go that far or have Wal-Martphobia Walgreens has it for $5.99. I imagine H.E.B. also has it.
