As a veterinarian for 35 years, I have learned that it is too risky to keep your beloved pet in the back of a pickup truck, tied in or not. It does not take much to break them out and injure them. I see it all the time. Keep them inside with you or leave them at home.
That is a pretty great idea. I am not very good with electricity. I found this at home depot. Do you think it would work the same. parkworld 25 ft. 10/3 RV 50 Amp to 15 Amp Tri-Outlets Extension Cord NEMA 14-50P to(3) 5-15R Adapter Cord 886245B - The Home Depot
