Think some of you guys have seriously gone off thread topic.
The thread is about "Need a back up machine what do you recommend".
OK, I initially said something like - get a Scorpion 3 vac, and use your Prochem as a backup.
That to me was a much better option then getting a backup machine (presumably of less power) to the Prochem they already have.
A truckmount is hardly a backup machine. Even my Scorpion is a back up to my Prowler.
Now the thread seems to have developed into the old battle of "heat against no heat"
But a truckmount is not the be all and end all.
There are many, and I mean many portable owners - some on the forums, more not on the forums, who make a good living from a portable. OK they may not do all that Peter has done ie night clubs, pubs, hotels, conference centres, trains, ships, offices, houses, restaurants, nursing homes - but maybe they can make a very good living just doing domestics and smaller (or not so small) commercial jobs, many such cleaners have a rotary as well and engage in commercial with that - doing a good job to customer satisfaction.
So blowing the truckmount horn at full pelt is not telling the full story.
The two truckmounts I have owned may not be the all singing, dancing most powerful units available, but having used them I do know that they make carpet cleaning easier. But like I said, IMO they are not the be all and end all.
You CAN have a good life with a portable.
