OK, putting all this together, this is what I see as an adequate 20x24 setup.
First, forget the pickup. Better use a Hummer. More room in the bed to move around in. Plenty good for rough terrain as far as vehicles can go.
Second, for the places the Hummer can't get to, three mules. One for the camera gear, one for camp gear, one to ride and lead the other two mules.
Third, a horse trailer to move the mules with. Guess we need a four-horse trailer since we have three mules. Going to need the fourth space for the water, feed, and shovel.
And of course the barn and acreage to support the mules when doing Hummer excursions exclusively.
Anything I forgot??
