We have used mountain bikes and bike trilers in road closure area's since the 90's. About the farthest we pack in is seven miles as the crow flies-more like nine as the bike rolls.
We mostly use center pull trailers that bolt to the seat stem like Blue Sky's and the old Huffy Ride and Runs. One of the guys attached a hitch stem to a Cabela's Magnum game cart and used Blue Sky parts at the attachment point on the bike. It works well and may be the cheapest way to go.
The bike trailers that attach at the axle work on the roads but snag in the brush and are hard to use as carts.
We use the bikes alone to wheel game out to a bigger trail if the game is in a place where trails are narrow/brushy.
