Alright so I know the solution is warm it up but where I live right now it is -45 celsius with the wind chill and will probably get colder. My tonno is a Roll-n-Lock and it is not the automatic one. When I try and open it it is not the gasket part that keeps the water out that is frozen but the locks that attach to my tailgate that is frozen (well I think, I have not got it open yet). Anyways I was just wondering if you guys had any tips so that this does not happen again, short of running two interior heaters into the bed of my truck. Thanks for any help!
