HappiJac 4500

I had the same thing happen 2 years ago when I was about to load the camper for a long trip. I ordered a replacement from Tweety's. The correct replacement was a Happijak 4800. It seems identical except slightly longer to compensate for the higher sides on many new pickup trucks. The cost was $313 including tax/shipping. They shipped the day I ordered and it came on the second day after I ordered. I have had several good experiences with Tweety's and suggest you give them a try next time. Sometimes there is no price difference but they seem to be very technically knowledgeable and orders are shipped and received very quickly.
