Thanks Matt,
I am very pleased with the quality of the toolbox, the only thing I could pic would be the side doors adjustable lock bolts needed an extra bolt to stop them rattling loose.
I used the gas bottle mount plates, with two nuts/bolts one each side to hold it down and in place. I also used 4mm steel plate as washers inside the box. I also put a stip of 6mm rubber between the box and aframe, to stop any rattle, movement and also take up then space the checker plate causes steel on steel. For the gas bottles I put them smack in the middle using new shorter holders with some more 6mm plate as washers underneath, also bolted holders together. For the gas regulateors I had enough spare main pipe to simply unwind it, and put in some braided lines, with rubber adhesive tape (TV tower cable tape) and silicon to through the wall in the box.
I have a bit of left over rubber I am planning to throw on the floor of the box.
I must say that having the extra space is dam great. Put all my tools, welder, 4.6kva gen, drill, wheel chocks, level ramps, annexmat, Gerrycan in the box which now leaves the boot empty for my BBQ slide (still in progress), and hopefully soon a 200ah lithium battery and victron 3000 multipass.
Cheers Iain.
