As far as improvements to the truck, I don't think
AT has anything revolutionary, Vlad's big add this year is his Vladiator Spears, they enhance the existing Heat Exchangers, it's a common enhancement done in the boiler world, for some reason it's new to carpet cleaning trucks.
The big things you will see in the future on these trucks are from the guys buying them, guys like Michael Schoeny who made changes and designed improvements ( the 3 jug system is just one of his many) but even he has since made another change to make the next generation 3 jug even better, not to mention the other things on his truck, I think this year's Vegas Connections will be very interesting.
