Hi all, back after a few years absence
My Brake Buddy just imploded, and I'm reconsidering the whole thing before buying again. My GVWR for the Winnebago Adventurer (gas-powered) is 20,500 lbs and the toad is a Jeep Cherokee, curb wt 3600lb, so I'm nowhere near the 25% mark.
But my personal horror is barrelling down the 1-95 in traffic at between 60 and 65mph and being called upon to stop. Slowing down is easy enough but a full panic stop is something else again. I have no illusions that the front of the Winnebago will protect us much in a pile-up although having the engine up there in front is some comfort. No airbags, though.
Brake Buddy has a good deal on. Send them your tired and broken Buddy and they will send you a new one for $495, tax free and free shipping (one way). Seems like a good plan.
