Yeah, that's the problem with caps, toppers, and cages--they're hard to get on and off if your truck is a multi-use farm vehicle and you also haul goats in it several times a week. It's a good thing we live in a place with lots of sunshine so my guys don't really need a roof when hauling. We blanket them during winter hauling if the trip is longer than 20 minutes or so. I suggest blanketing any goat being hauled in an open bed (tied or in a cage), especially on the highway. Wind chill can be brutal. They either need a proper enclosed shelter or blankets if the weather is cold. If it's raining or snowing, they need an enclosed shelter unless it's a very short trip.It is impractical to remove the cap, so I can only cram about 20 bales in, if the tail gate is down.
