We started our toad experience with a Roadmaster
Explorer. That's the kind that stays on the car and attaches to
the MH via a ball hitch. It worked but when I watched my brother
and several other people hook up using a motor home mounted tow
bar, I switched. We now use the Roadmaster Falcon and far prefer
it to the Explorer. We have a cover for the tow bar but do not put
it on unless camping. At home the rig stays in the pole barn so
there is no need for the cover.
