Hank couldn't move when he woke...he was too tired. He fell asleep, that's the last thing you want to do when you are trying to defend yourself. The RV was still broken down, and he couldn't walk down the streets of England with a shotgun in his hands. Even the Revolver was risky here. 
He put his Ax into it's hidden pouch in his jacket and put his machete on his back under his jacket so he could still carry both.

He grabbed a small bag from under his bed full of emergency supplies, enough to last him a few days. He put the revolver in it and left the RV. He was armed, though he didn't have most his gear right now, he had the Night vision goggles in his bag but that was it. Truth be told Hank was scared, he messed with a lot of vampires, would they come after him? And what would they do to him once they found him? Would they kill him? Would they torture him? Would they sever him limb by limb? Would they drain him dry? Would they turn him...then kill him using his own methods? 

Hank hated the idea of becoming a vampire, he saw what it did to people, sure some vampires had control, but others...they were just...they lost what made them human...

It's not the fangs, or the urge for blood, or the immortality that makes vampires not human anymore...It's the will to kill everything in front of them to keep up their power, Their ability to kill other people with ease. So in a way Hank knows he isn't far from that point.
