Havnt got it yet.
I have a buyer for my TM (paid for) but he is getting a van (Soon)
Obviously cant put the Prowler in until the Avenger is out.
Water tank will be a vertical 400 litre baffled and mounted behind the driver/passenger bulkhead.
Then the Prowler behind that, across the van, access thro the sidedoor - like the Avenger.
No hose reel. To quote Derek - there for girls (have you got a reel Derek)

I hang the hoses with bungees from the roof - that was a tip from John Kelly.
Will post photos as soon as.
If you go to the Amtex website
http://amtexequipment.com/mvp/prowler.html and watch the videos.
One is of a Prowler 15hp mounted on the back of a 4x4 and there is also one where the waste water is draining into a container. As most waste is turned to steam, not a lot will be collected - therefor not a lot to dispose of. Its the last of the videos-has the green prowler, all interesting.
This added to the reason I went for a Prowler.
