G'day Geoff Many thanks for the reply, it's not easy to rattle the cage sufficiently to elicit a response on this forum, as you may well find out! It was actually suggested by a mate of mine who drags a biggish Jayco around the place with a cruiser, but not a 200. It's not something I'm willing to jump into unless it can be proven that it's a necessity. However, on another note, it has been suggested on this and other forums about beefing up the suspension to increase the vehicle's GVM given that there is potential to exceed the manufacturer's GVM, particularly when towing a big van. Have you found it necessary to consider that option to give you 'more fat'? There are other threads on this subject on this forum. Regards Tubby
