Thanks for the welcome - I knew this was a friendly forum.
We have an Aliner club in Australia but I like to look over the fence and see what our neighbours are doing.
The wind kit I mention is the one that is designed to stop the Aliner coming apart in strong winds - never seen one in Australia but you lot seem to talk about them all the time, so I figured I'd see what you blokes do.
I tow with a Ford Territory which is an Australian based SUV design about the same size as your Explorer - has a straight 6 190Kw petrol engine.
I'll attach a Picasa link to show what my van looks like - excuse the pics of the grandkids.
