Thread: Upgrading caravan suspension

So far my research suggest that I would need to add a secondary chassis to the existing one and the size of the material to be 50 x 75 duragalv, then using 100 x 50 for the new draw bar. The new suspension unit is going to be a premade coil independent unit.
Is the size of the material the right size or do I need to use a larger size and where would it need to be used ?
Cheers Alby

Hi Alby,
Is the van going to be an Off Road type of vehicle? If yes, the dimensions for the second chassis should be fine, I personally would go to 125 or 150 X 50 X 3+ for the draw bar. If an on road van, the secondary could be 50 X50 X 3 and drawbar 100 X 50 X 2.5+ should be fine.

Thanks for that Kryn, I'm hoping that I'll be able to catch up with you somewhere within the next 14 days.
Cheers And thanks for the advice. Alby

Hi Alby, How is it going with this conversion, I think we might have pulled up next to each other at the traffic lights in Murray Bridge, there was a Nissan Patrol? with a plate similar to your tag, unfortunately I was turning left and you were going straight ahead.
