Chris,
Thanks for the name, it makes all the difference.
The prime difference between you and me is that I have experienced both sides of the coin, where you clearly have not. You only assume your point of view has some validity because you have never actually owned a Truck Mount and therefore everything you say in relationship to one is nothing more than pure conjecture.
One thing that has always baffled me is why the portable lobby feel so well informed about a technology that they have no direct experience of and then try to argue the toss with people who have been where you are with a portable, saying all of the clichéd things that portable operators always say when confronted with a Truck Mounter, trying desperately to justify why they don't need one, even though they know that they do.
Do you honestly think that people would shell out tens of thousands of pounds on TM's if there were not some good sound, business, economic case for doing so, or is it the case that only those who have no direct experience of the same situation are miraculously better informed than those who have.
Do yourself a favour Chris and talk to us about things you actually know something about.
Oh, and BTW, did I mention that not only was I the first person to have the original RX20, 21 years ago, I was also the first to have the first of the heat exchange technology truck mounts, the Prochem 75HE and then the first to have a twin capable heat exchange Truck Mount, the Prochem 800A and the first to take delivery of its successor, the Prochem Performer Bear Catalytic, the first catalytic truck mount. And then more recently the first with the new High Efficiency RX20 and most recently the first company in Europe to operate the Hydramaster Titan. Now you, Chris will just think I'm bragging, whereas others will see the steady thread of commitment to being at the very forefront of technology and the really generous will quite happy concede that on the Truck Mount front, this guy probably knows what he's talking about, but do feel free to correct me if I'm wrong, as I am sure you will.
Simon
