I used to have a crew to do mobile homes. now I only do them out of desperation, they are a big pain in the butt. with little if any profit. the clean up is worse then a regular house destruct, and its worth at least a thousand to just pull the floor. the gravy ( the frame) in any thing newer then 1985 is a joke. 600 lb for medium maybe 1200 for big with axles, and you will be lucky to get #1 for most of it.
