Here's a small but simple mod: strips of non slip tape to clamber up the big step and up onto the bed. We did it for the dogs first, actually, their little paws were slipping and now they've lost their jumping mojo! No doubt, they will get it back soon.
One more weekend, and we've got a trip down to Katherine and see how 6+ hours of highway travelling with a trailer is on fuel economy. Nothing very exciting though, just camping in the front yard of Paul's dad's place!
