Our fifthwheel only came with a power fan in the bathroom and we have not forked over the money yet to have any installed, maybe later. On our last trip out it got into the mid 80's and the breeze coming through the windows was not enough so out came our Fan-Tastic Vent Endless Breeze 12 volt box fan, they are only 14" fans but put out 900 cfm on high and it did the job. It ran on low over night and drained our battery 6% which was acceptable for staying cool.
Power consumption: 1.2 amps - 2.6 amps
Low Fan Speed = 1.18 amps
Medium Fan Speed = 1.62 amps
High Fan Speed = 2.58 amps
Well the Boondocker BD-1275-C 75 amp battery charger I installed for our batteries worked great, after 2 days and nights I fired up the gene...
I am going to post cool places to go in Montana & Wyoming, the first will be Kirwin WY ghost town & the DD Ranch on the way to it....
