Renting vs. towing may well be dependant on how long you're on the road. When we bought the MH and traded in our truck and TT I was forced into that decision very quickly. Yes, I used the ~$250.00/wk number but still it came up to shelling out close to $4000.00 in rental fees which were out the window with nothing to show for it.
I finally decided to buy an inexpensive but reliable toad that would tow easy and was simple/cheap to install the necessary stuff to make it towable.
Long story short, for less than 5K I got the toad, tow bar, brake assy, brackets, wiring, and everything. Now granted I could have spent 1K less by renting but now I, at least, have an asset to show for the expenditure.
