Great White had to be towed to the shop a few weeks ago because it wouldn't start. It turns out that, because it hadn't been driven for quite a while before we bought it, one of the engine seals had dried out and split and was letting air into the engine. The shop fixed that and got the retarder brake going again and now Great White's as good as new and purring like a kitten. And home. And ready to pick up the 5th wheel at the end of the month.
