Nearly there Tony, i started by taking out ply lining and putting new back in, with 1" of quintherm insulation behind it and under the floor. Just thinking ahead for cold weather, too many expensive fittings !!
Need to drill into the tank for fill fitting, holes to drill into frame for mounting, and a hose to replace from blower to waste tank. Then off to my mates to lift it all into place with stacker ..
Hose reel to finish rubbing down and paint, then bolt everything thru chassis, oh and waste outlet to move, will tuck nicely under curve of bulkhead on floor.
Now thinking have i missed something :

Cleaned 15 kitchen floors earlier in week with spinner attached, was a nice little earner, almost paid for itself
