Hey all

Im looking for some input on a problem I’ve been having. Any advice or suggestions will be welcome.
I hunt mule deer in September and October and do several 4-5 day trips where I backpack in and set up camp. Then do day hunts from camp.
When I shoot a deer early on in the trip and I have to pack the meat back to my truck ( after a night to cool and hang) which has a large ( 110L ) cooler in it.
I know that it’s not great for meat to be moist in the cooler and the drier I can keep it the better
All my ice is frozen in water bottles but I find as the ice melts water forms on the bottles and gets the meat wet. What do you guys suggest for some kind of moisture barrier between the meat and ice? I know I can’t wrap the meat too much cause that would keep in heat but I need to improve on my method of storing meat

Thanks
