Composting toilet install

We're just starting a new config (Ford Transit 350 HR) with Sportsmobile North and we would like to use a composting toilet (probably an Airhead). They told us that they would not install it - does anyone know the reason for that (since it bolts to the floor with 4 bolts . . .)?

Also, any suggestions about vent locations? I'd hate to put another hole in the roof :-). I found some earlier forum threads that suggested venting through the floor, but I'm not clear on how that might work . . . particularly since you would have to seal any vent pipe penetration in the shower floor!

We vented our Airhead through the side of the van since we have a penthouse top. I was concerned that odors but it is a nonissue. There are no foul smells. We also mounted the toilet on a teak floor mat so we didn't have to penetrate the shower pan. It's worked out great for 1 year+ we've been using it.

I'd second the previous comment - we install nature's head toilets in the travel trailers that the company that I work for makes. We install them on teak mats (you can cut the teak mats to size) so that you don't have to bolt/screw anything in to your vehicle. I'm not familiar with the Airhead, but the nature's head very easily vents out the side. We run the flexible hose the toilet comes with in to a 2" PVC pipe that goes through our subwall. This is covered on the outside by a standard 2" PVC vent cover.

Thanks very much! I'll talk to Sportsmobile about running the vent for me. And I like the idea of the teak mat - I was definitely concered about bolting through the shower floor!

I'm already comfortable with the "technology"; we've had an Airhead installed on our cruising sailboat for the last 8 years :-)
