I've never been thrilled with my rv's brakes. So, I took advantage of Dexter's self adjusting brake special at the Gillette Rally. Spent the last two days installing same. (too hot in the afternoon) Found one unattached wire. No wonder my TBC kept going off and telling me I had a trailer wiring fault. Now for a test run before we head for Parry Sound, Canada for the Great Lakes Cruising Club summer rendezvous.
