The weight and braking capacity should be large enough to handle both vehicles in an

emergency situation. Check your towing vehicle manufacturers recommendations for towing,

hitch load, and braking capacities. The hitch, ball, motorhome chassis, and safety cables

(each individual cable) need to be rated at a minimum for the weight of the vehicle being
