Having once had a baseplate fail and watched my Saturn slowly pass by my motorhome (luckily on a back road with no traffic at the time) I would not take a chance. Personally, since I like the ReadyBrake, I would have NSA send out the new piece ASAP. Then I would document the problem with the old piece, and again request a refund. If an agreeable settlement can't be reached, I would write to the NTSB, the Motorhome Magazine Hot line, FMCA hot line, and anyone who will listen, and perhaps look for a small claims settlement. (difficult because of state lines). But most important, get yourself safe so you can continue to have fun.
