If you intend to live in your MH fulltime then I would forget the idea of a B. I would look at a C or A say in the 28-30 ft. This size is easy enough to drive, get in most campsites, have decent storage, and actually give you enough room to turn around in.
For your price range you will be looking for something in the mid to late 90's, less expensive and you're looking at even older units. In either case you need to be handy at fixing things. Go to someplace like RVT.com and do a search for MH in your price range and you will find lots of them.
I have seen MH's hauling motorcycles with a hitch mount, others towing on a trailer should not be an issue.
