Welcome to the forum. ask them to explain how the tv works, the dvd , the outside speakers ( we played a movie to the neighborhood once!
) the check list is good, look into every nook and cranny. We bought a 2013 Solaire 267 BHSK and we absolutely love it! headed to Gulf shores not this weekend but next weekend! Also Be sure to have them explain how the thermostat works for the heater and ac, i thought i knew and lo and behold you can run both at the same time!
