This may sound really stupid, but there is a good reason and logic to it... Get the movie "The Long Long Trailer" (Lucy Ball and Desi Arnaz) (1953). It a time honored classic. But beneath all the slap stick humor is a VERY serious message for RV enthusiasts. Watch, listen, and learn (in a fun way), but this movie covers ALL the basics of RVing with a trailer.
The second is Robin Williams, RV-The Movie (2006). This story takes place with a motor home. Here again, lots of slap stick humor and a couple of themes running through the story about family relationships and one's loyalty and dedication to their place of employment (which by the way, ends with a very good ending). But under all the comedy is also a very serious undertow for RV enthusiasts. Lots of "Do's and Don'ts" and the over all movie, if pulled apart from an RVer's perspective is chocked full of tid-bits. Aside from the family-work relationship, is also dealing with other campers, dealing with the logistics of an RV (which is where most of the humor comes from), dealing with choices, campground etiquete, traveling, finances, and a bunch of other issues.
The non-RVer watching either of theses movies would probably just brush them off as dumb comedy. For the serious RVer, there's lots and lots to be gained by them if you approach both movies with a very serious RV critical eye.
I watch both movies at least once a year. Not so much for the comedy value, but because there is just SO much in these movies, I'm still discovering little tid-bits I've missed that are so true. And the older I'm getting and the more I travel with my camper, the more these two movies mean to men.
So, if you can get a copy of them, sit down with a big pot of pop-corn and a drink with your spouse and enjoy the comedy. Then wait a couple days and sit down and watch with a paper and pencil and take notes! You'll learn more from these two movies combined than tons of reading.
My advise... Watch, and learn!
