I like MUDMAN or MUDNTOY
I've been trying to come up with one for my rig. My van was easy, IRISHK9, thought about my kennel name for the Jeep MAGMA or MAGMAIW, then wondered about
GRNMCHN or GRNWCH.
When the right one comes along you will just know. At least that's what I'm
hoping will happen.
Good luck, choosing is half the fun!
