Hi all. Just bought a used 2010 Jayco Expanda Outback 16.49-1HL which I haven't picked up yet. Our tow vehicle is a 2006 Ford Territory GHIA with a newly fitted Hayman Reese 2300kg rated tow bar. With an empty ball mass of 147kg and a GTM of 1850kg, I'm concerned I'm going get a bit of 'sag' in the rear as like when we were towing our 2018 Jayco Swan which was considerably lighter, albeit on the standard Ford 1600kg tow bar that I've replaced. The weight distribution might be different from the the Swan to the Expanda and I won't know until I hitch it up, but any suggestions? WDH or Airbags etc?
