We have done the covering with blankets and towels etc which really seems to help. Our setup is always inside the truck bed with the folding panel bed cover in place...
We also fill the 5-day ice chest with ice and use a small 2-3 inch plastic snap container sitting on the top of the ice for the things we don't want to get water logged.
We do rather well with our 5-day ice chest for keeping ice... Keeping the ice chest out of the direct sunlight is the big answer for us.
My 5-day ICE CHEST sits next to our generator in the tailgate corner of the truck bed for easy access... You can just see the extra blanket covering the top of the ice chest in this photo... The generator is only pulled out for three hours aday usully at 8AM each day with the most of the time the tailgate and top bed panels are closed up and locked.
