Ian, no point putting the tank in the Sprinter, it's been plywooded over, and the anchor points aren't accessable.
Main problem is it's way too big to take down anyone's drive in Brockwier etc...
I'd have to park it somewhere out on the road (probably miles away!) and walk with the ladder.
I'm going to have to do somewhere else this week!
I don't know if I can put that coating in the van, and if I can it needs to be done in one day including all the fitting out.
I can't afford more than one more day off when it arrives.
I can't see I'll need a bigger tank.
I'll be able to totally fill it now, and surely 400L is more than enough.
Main problem is the hoses were cut to fit the pump very near to the tank, and I'm not sure it will be...
I guess it'll all have to be worked out in a new layout.
I'm sure you'll be able to help though.
Cheers.
Oh, and Tacky...a balloon payment is a final payment to own the van, but I'll have the equity of the van to put it in for a new one.
