Found JT's Strong Arms on Amazon with Amazon Prime ... beats the local store price, because the store didn't have the 5th wheel over 58" kit in stock. Then found a new non-prime vendor on Amazon ...
Once you get it and install it, you are going to love it! Best $255 I have spent for my new camper. Don't forget the extra mounting plates (#314597) for the rear if you have the electric stab jacks!
