hi
is a payload of 610 enought for a 350ltr tank purefreedom trolley and ladder ect
any help would be great
I think you would be running things pretty tight myself if you want to fill that tank. OK, if you are a lightweight, carry the minimum of equipment, and keep the fuel tank lowish you may well be OK with it. I reckon on a minimum of 500kg over and above the weight of the water for a single operator. Mind you, I am a Billy Bunter and I do carry a fair bit of kit at times.
Tip: Load all the kit you would normally carry, fill up the fuel tank, and while sitting in the van, get it weighed at a local weighbridge - while empty of water. Deduct the weight on the bridge from the gross vehicle weight and that will tell you how many litres you can put in that tank (1kg per litre).
