I thought I'd also mention that I filled 5 Jerry cans with 100 litres of fuel and put them securely in the back of Pearl. There was a noticeable difference in how Pearl handled with the extra weight of the 5 full Jerry cans. I imagine it would be much worse with a long range tank if there is no change to the suspension. So I am researching suspension modifications for both front (because I have the bull bar) and rear (because I eventually want to fit a long range tank). I am thinking of height adjustable air bags for the rear and slightly increased load capacity front springs.
