Will it fit?

I posted this on the 503 also, could use your help too. I have an F-350 with a utility/service bed, 48 1/2 inches wide between the tool boxes. Will a mule squeeze in there? My main concerns are the bed rails and the lifting rings on the axle hubs. Does anyone know for sure if these would be less than 48 inches? Thanks for your help, Tom

I measured one of my A2's and it was a little more than 51" hub-to-hub. I think you will have a problem with only 48 1/2"
