I have a D40 Navara 2010 and have just bought a 2012 Jayco Starcraft Outback. I have fitted a Hayman Reece WDH to the Navara but am concerned about the ground clearance of the spring bars once attached to the van. The draw bar on the Starcraft is down between the drawbar rails, not on top and I don't know if this is causing the issue. Any advice would be appreciated.
