Our 21'  Bigfoot Mods and Embellishments.

Sunset at Boardman State Park, Columbia River, Oregon

Our first two "stick-built" trailers were disasters.  After suffering through the major repairs that resulted from crummy design and construction, we decided enough was enough. We wanted sturdy, hail and dent “resistant” construction that wouldn't leak. That ruled out every contemporary aluminum clad trailer right off the bat.  We even looked at a couple of used Airstreams.  Despite the deluxe interiors, loosening rivets and fragile exterior skin eliminated those, too.  After crawling under some of the deluxe fiberglass paneled units, we confirmed that they were little better than their aluminum-skinned cousins.  It became obvious that molded fiberglass construction was all that remained.  Because our last trailer was a 19 footer, and that size and feature set (larger water and holding tanks, etc.) seemed to fit us well, we started checking out the Bigfoot line.

Because of the capricious nature of RV nomenclature, the Bigfoot 21' trailer body measured almost to the inch the same as our old 19' Sandpiper.  By sheer luck, we found a 2002   21'  Bigfoot on consignment in Sacramento, CA.  It had never been used because the original purchaser couldn't get it up his driveway.  Fortunately for us, unfortunately for the buyer, the dealer figured that one trip home and back made the trailer "used" (though the paper seal was still on the toilet), with the consequent drop in retail price.   So, the used trailer, on consignment, got buried way out back behind all the high-priced stuff.  A quick query on the forums at www.fiberglassrv.com confirmed the price was good, despite being 50% more than that of a similar sized new stick-built trailer.  But we expected that.  Besides, we reasoned, the time and cost we saved not fixing could be spent on the road.  We made a deal and drove our "new" Bigfoot home.

. . . then we promptly set about fixing again.  Only this time it was "improving" fixing, as opposed to "repairing" fixing.

Molded fiberglass construction is simply a superior travel trailer design.  Bigfoot has chosen to use a two piece upper/lower fiberglass shell arrangement, bonded together at a "belly band" that runs the entire circumference of the trailer.  The lower half is entirely one piece fiberglass, just like the sides and top.  The only penetrations are for wiring, gas lines, and plumbing, which are all sealed.  (With a good fitting storage hatch and entry door, there's no reason the trailer wouldn't float indefinitely.)   This makes the water infiltration and associated troubles commonplace with conventional stick-built RVs not even possible with the Bigfoot design.  Unfortunately, the attention spent on the snazzy design and engineering has not extended to the assembly line.  Despite the above average interior finish and materials quality, the inside needs a bit more thought and planning applied to where things go and how they're installed, the whole product would move from being quite good to near perfect.   Of course, it that was the case there wouldn't have been anything left for us to do...

So, here are a few mods and fixes we've done to our 21' Bigfoot to make it often better, and if not that, at least uniquely "ours". Some are trivial, some are difficult, some are easy. Some are unique to our rig and others can be found elsewhere on the web. So far, they've all worked and contributed to the fun we get from traveling around the country. 

Feel free to borrow anything you can use and don't hesitate to pass back improvements, comments, or ideas of your own.
