For safty use copper to get the end of the rubber hoses out of the truck bed.problem solved-I had a heater in my truck bed for my dogs years ago in MA. they were broken hearted if I left without them.I even took them out snow plowing-but they rode in the cab then,1 with me and one with one of my drivers-hard to plow with 2 large german shepards laying on your lap. Use as large a heater hose to get better flow as possible. I used a heater out of an old 40s chevy with a 12 volt motor installed in it.
