The height increase looks like even more than you would get by going to a straight axle
, but maybe that and a spring mount change would account for it.
I called the local Bigfoot
dealer. The sales guy there was familiar with the Extreme, but said they would not be available for some time. He had no technical information, and I think all he has to go on are the same photos we're looking at. He also wondered about the practicality of the brush guards, since they could catch on the very branches they are supposed to be guarding against, and rip holes in the shell.
By the way, he suggesting that if you really want off-road ability, you want an Earthroamer
(no, he doesn't sell them). For us "lightweight moulded fiberglass RV" fans, note that Earthroamer has supplemented their line of heavyweight F-450/550-based models with a little Jeep-based unit, the EarthRoamer XV-JP
. Even this little one is much more expensive than a Bigfoot
trailer, but it's half the price of its big brother...
