tow pkg.?,TOWED pkg. !

many vehicles can be ordered with a 'tow package' ; provisions for trailer lights,brake controller,tow mmirrors,etc. makes it easy to pull a trailer.
how about a 'TOWED' package? for those who want to tow the vehicle,like behind a motorhome. provisions to plug in the rear lights to your towing vehicle,a tow bar,and take it one step further-how about lock-out hubs built into the front wheel drive axles of automatic trans. vehicles so four wheel flat towing was harmless to the tranny? seems to me the technology already exists for the lock-out hubs,why not market it in a new fashion? that cumbersome two-wheel tow dolly can go to the scrap yard.
