Spare tire under garage

I got my toyhauler and while we 'saw' the spare tire hanging under the back garage, we didn't realize just how low this thing is :)

when hubby backed up into our yard it is a slight downgrade. boy oh boy that tire skimmed the grass. I stopped him, he got out and put his hand under the tire and figured we had a teeny bit of room left.
good thing we got the camper set into its spot.

but now I am wondering if that thing is going to be a small nightmare at times?

anyone else have their spare tire bolted under the hauler? any problems you encountered?
thanks
