Hey Mike Kelley
, Oliver and Escape are all fantastic, well-built trailers. I would be proud to own any one of these brands. But they have some fundamental differences.
is the only actual 4-season trailer of this group. This category includes good insulation, double-pane windows
, enclosed tanks, AND a ducted heating system that circulates to the plumbing and tanks. Depending on where you live, you may not need this much winter camping capability, but Bigfoot
The last I looked into the cold-weather upgrades from Bigfoot and Oliver, they do not include the furnace
system that ducts heat to the plumbing and tanks. Very few actually need this anyway, unless you are camping in extended below freezing conditions. I have spent time in late season hunting camps that can be sub-zero for days. The Bigfoot keeps everything working - as long as I keep the furnace
Another difference is the width of the cabin. The Bigfoot is the only one with 8 foot width. I believe most other FG trailers are around 6 1/2 feet. This may not seem like much, but a little width adds a lot of spaciousness. Way easier for two people to pass in the aisle, for example. On the downside, the width catches more wind on the highway, and it's harder to see down the sides when backing. Oliver and Escape are both more aerodynamic than a Bigfoot which can help with mileage and handling.
I have toured Olivers and Escapes and they are really well-made and appointed trailers. You would be happy with either one if you find the right deal. At this point in my life, camping in sub-zero weather isn't something I need to be doing either. So my next trailer may not necessarily be a Bigfoot.
