An RVer shows off his small trailer and explains how he lives both frugally and with respect to the environment. Not only will you find this interesting, but during the tour of the man's RV you will learn something about RVs and their systems that you may not have known before, no matter how long you have been RVing. Even though the RV's owner says the RV is 150 square feet, it looks larger than that to us. . . but not by much.
