With your 2007 Bounder you have either a Ford or the GM engine. I had one coach with the 8.1L GM engine and I have one suggestion which is to switch to a 2 quart oil filter. Besides giving you extra oil capacity and extra filter capacity, it allows the filter to hang low enough that it is very easy to get to with an oil filter wrench. The larger filter costs about $2 more than the standard 1/2 quart filter. Remember to fill it with oil before you install it. For all I know the same thing may also work on a Ford 6.8L engine.
