NWH - I'm on a traders policy and insured for window cleaning use on any vehicle but phoned them anyway and they are ok with any modifications
Daz - I'm leaning more towards the connect. As long as its not pushing the payload the 500l sounds great. I had 350/400 in mind but an extra 100l is the way to go I think.
Cheers guys
danny the connect T230 is like a tardis inside!i was pleasantly surprised just how much room there was!the high roof allows you to fit a couple of pole holders(i use soil pipes from B&Q secured with zip ties)500L upright tank and frame fits in with ease with plenty of room left for trad gear,pumpbox,backpack,reel etc.i had mine fitted longways which allows you to fit stuff down the sides.
it pulls well with a full tank.im probably just under the payload limit first thing though but obviously it gets lighter as the day goes on.
mine has the mesh bulkhead which is great.also they have a shelf in the cab above the windscreen which is handy for storing stuff like gloves,caps/hats etc.2 cup holders and plenty of little storage compartments.
