It depends. If yours is a bus than it should take a special anti-freeze with an additive. Double check what it needs!! Ours does. It takes exactly what the semi's take so therefore a truck stop for us for the anti-freeze. As for the rest of the "misc" stuff we get from various places, very rarely do we take a trip to walmart.
For parts for the engine, most of the time we can get the same thing from Auto Zone or the like and for much cheaper.
For replacing the thin-lites lights over to LED we shopped around, got some from Marine Beam for a straight switchover but for the others Thom got LED strips and is experimenting with different ones to decide which he likes better for light.
So therefore it depends on what "misc" you are talking about.
