RV steps with holes punched in the steps are dangerous to pets. I travel a lot, and twice in the last several years I've seen a dog lose a toe nail and also end up with a broken toe. Those steps should be outlawed, and the existing steps ( which number in the thousands ) should be covered with wrap around type step covers. I don't know how to get the word out about this problem so, I thought I would start here. If anybody knows how to contact all the RV manufactures' at once it would really help. I don't know if anybody in the industry cares but it would be worth the effort. The last dog was hooked to the step for a few painful minutes before someone got his toe out of the hole. He lost the whole nail. Very terrible, very painful.
