Never done the MH/toad thing but one thing to think about is every time you go to a CG and have to back in you'll have to unhook the toad before you set up. Pull thru not so, so that may limit your choices a little. Not every boon docking spot will be a pull thru. Also I don't get the 'no place to sleep' if the MH is in for repairs. Has no one heard of a motel? Not the best scenario but if it's not possible to sleep in the MH just grab a motel for a night or two. The extra stairs in the 5'er could be an issue until your wife gets her knee fixed. I'm in pretty good shape but walking down the steps 1st thing in the morning is not a skip in the park.
