Well when we were looking for a used 5er we came across two a Keystone "Sprinter" Copper Canyon, and a Keystone Montana both with the Model 293 FWSLS. They both had the same floor plan, yes the Montana had better quality furnishings but the basic box was the same. We saved over $5,000 buying the Sprinter.
It didn't come with a Polar package, but I did find it interesting just this last month we were on the Oregon Coast and kept the 5er which is 32' long with a super slide and bed slide at 68 degrees in temps of 20 degrees outside using our newly installed Cheap Heat system which is electric and actually puts out less BTU's (17,060 btu) than the gas part of the furnace at 23,700 BUT output (30,000 btu input). I will be sealing and insulating the basement this spring as we get ready to go full time with this 5er.
