I was just messin with him. OBS's have more room than a SD, but I don't think I have any less room than a Cummins truck, only tight spots for me are on the firewall side of the engine. I get to wrench on those pesky Dodges all the time, I think they all have their own quirks and plus & minuses just like the Fords. I try to stay away from the Cheby's. don't want to get any on me :hehe:
