I am building a dog box tomorrow for my dodge Ram but wanted some insight from this lovely group as I am sure you are more familiar with transporting your packs in colder temps. The dog box we are building is for our 4 dogs (husky, lab, lab husky mix and our odd ball boxer). All 4 dogs get along great and will be housed in a spacious enclosure from NC to AK with rest stops and walking breaks every few hours along the trip. we are constructing the box out of 2x4 and plywood with 2 side windows and the main entrance at the tail gate of the truck.
My biggest concerns are keeping the dogs warm going through colder temps. We plan on insulating the box with straw/hay and changing it out every day or 2 to ensure its fresh and clean plus not wet. The box will be fully enclosed and sealed to keep the moisture levels down but my next thought was to install a small heater and power it off a power inverter.... Have any of you done something like this or would it be wise to steer away from this (due to overheating etc.)
Any input would be greatly appreciated.
