Ex-Shuttle Bus as Tow Vehicle

[fankhaj1]

I am trying to find more information on the possible conversion of an Ex-Shuttle Bus as a Tow Vehicle. Most have Ford power, usually a V10 or 7.3 PSD (some have 6.2L Chev diesel's). It seems like with my four children it would be nice to have a bathroom on the long roadtrips. I would be pulling a Travel Trailer behind it!

Thanks for any help pointing me in the correct direction!
