Harro we have only done 1 real trip in it since it was built up, that was following the darling so no need for a lot of gear and the fuel tanks were plenty.
Next year is a biggie and will have 5 20ltr gerrys as well as the OEM tanks that hold 180ltr and they are stored in the pod in boxes I have made.
The pod came like that, when I made a new "tray" for it to sit on I got the centre of gravity as low as I could, then when I decided on body blocks the cab was made the same as the pod.
No idea on weight as I have not fully loaded it.
PITA takin it off and on, its my toy so having a tray is not what Im after.
Used the steel tray to make a trailer for our work.
