Great idea! I'm going to check out those Apache cases from HF. Right now all I have mounted on my 18" Hooke Road rack are two 2.6 Gal fuel tanks on the drivers side and two traction boards on the passenger side. I'd like to use a case for tools and another one for recovery gear. I was thinking that if it extends too far out I could mount it on the inside flanking the tailgate. Good thing they have orange since I'm going with an orange theme on my JTW.
