I haven't had any problem with the double pane windows
. The tanks are enclosed below the trailer and the area is heated with ducts from the forced air heater.There is no switch because Bigfoot
doesn't use electric tank heaters on the four season package. If you find double pane windows
and enclosed tanks you have a four season trailer. I believe most 2000 or newer models will be four season.
When I was searching it was evident when a trailer was in good shape. With any older trailer there may be the need to replace/repair appliances. It is also wise to plan on spending on upgrades such as LED lights/solar etc. I would also check the axles, tires
, bearings, and hitch assemble. Be sure to check the roof to make sure it was maintained and there are no leaks
If you have the opportunity fill the fresh water tank and check to see if all of the plumbing is operational including the hot water heater. Jim
