From experience when first starting off ATVing, you don't want drinks or food slapping around in a cooler nor have water and ice slamming into same. If I need to keep something cold I use a small, soft, insulated lunch bag, drop in some frozen water bottles or ice in a zip-loc, drop in what I need then pack it tight with more frozen water bottles or bagged ice and a towel to make everything snug so nothing can move. Otherwise my camper fridg is the best place to keep things...lol
First, thanks for input and how you do things. I bought a 7'x14' cargo trailer and converted it to a Very Strong ATV/MC toy-hauler//Camper.
Since the interior was an empty box and looked for things to do stuff: fold-to-the-wall sofa-bed, propane stove, small sink, electric stuff- lights, batts, solar panels, insulation, roof temp-controlled fan, some sort of fridge, tie-downs, self made roof fishing pole holder, REALLY COMPACT shower-portapotty-room, TV-DVD player, selfmade TV digital antenna, and so on.
The Alpicool is a winner hands-down on doing the job without a big power drain. I go into the mountains and the battery/solar panels is it, no plugs for 150+ miles. OK, fine.
I understand about stuff in coolers smashing into each other. Don't like, not worth the grief, and beer can't take it. Live and learn. Regular upright fridges in campers are power hogs and not great. Just my observation. Alpicool any day is a good deal.
I carry usual tools, some special tire tools, air pump, Jesus Tape ( Duct Tape - Jesus I hope This Holds), nuts and bolts, tie wraps, and things of that nature. Something not good is bound to happen because you are not on your own front yard or driveway.
I agree that if it is too big a problem, just bring it back home. Fine. I just thought there may be other small things that might happen. One wrinkle in that premise is if you are alone. I have a Maadsdam Rope Puller with 100' of rope if the winch or battery fails. It is sometimes needed in periods of impeded progress - like being stuck somewhere. Since you are in NM, you know what "we consider difficult" in mountain/desert states is different than some folks have as "difficult".
I was also considering a friend who has ATV with ~400 miles on it, 4 years old, and has NEVER done a thing to it. By "a thing" I mean oil changes, air filer changes, adjust, ot anything. We are to go to Moab Canyonlands area. These areas are NOT a piece of cake. Things happen and break out there even with some caution. Hmmm, not my style.
Whatever. Go out and play or hunt or fish or run mud holes or something. If not prepared you pay the "experience" price.
YMMV
