dray,
If it hasn't have one already a coolant heater will help with cold morning starts, the hearter if set to go off 2 hrs before starting will warm everything up. (good electric receptacle a must, timer mite be needed)
For keeping it warm while running, bra with closable flap or your choice of materials to cover most of radiator area. Sorry can't remember percentage of radiator that must remain uncovered for proper cooling.
Make sure batteries and intake heaters components are in great shape.
