any type of cover over the radiator to up the temp a bit?
Always use a winter front when traveling in the cold… Gas, diesel or whatever… It doesn’t take long for fuel lines to gel… I’m not sure what its like in the US, but in Canada, the gas stations will switch to a winter blend of Diesel to prevent gelling… I believe that the switch occurs as soon as temps start dropping to < 32F... Carry a bottle of diesel anti-gel with you (but check to see what Cummins recommends).. You may want to make sure and run down your tank of diesel that you've bought in warmer climates (once again this comes from sheer ignorance of how things work in your home area), and fill up once you hit the snow belt...
