I agree, it does get old having to order every dang thing you need for our trucks. I guess trucks are not a big enough item for stores to specialize in these parts. At least not around my hick town anyway.
I don't really mind ordering too much, but the shipping is high sometimes, especially on low price items. But sometimes you can gain it back on not having to pay tax.
I guess this is what we get for having/doing odd ball stuff to our trucks.
