Hi we just joined and wanted to let you know that we have travelled with our 3 dogs without problem so far. We have 2 American bulldogs and a shepherd mix all of which are 70+ lbs each. We are fairly new to class A but have been to Ft Pickens (national park), Blackwater state park, and Desoto state park in northern Alabama without any restrictions or fees. I am aware that some parks do have restrictions so I always plan every leg of our trips and make sure we have all our vet paperwork with us if there were any question. So glad we joined this forum!
