Well after looking at costs to lift and hearing the stories about scraping I am going to pass on this unit. VERY sad as I have been looking for a long time and this one meets all my requirements with the exception that it is a little more than I wanted to spend but for the condition I was happy to spend the extra.
I still want a van as it will help with my work but I think I will keep my eyes open for a Sportsmobile or even a converted Astro (if it has low mileage) that I will have higher ground clearance with.
Back to the drawing board, or in this case the for sale ads.
