The heat sticks around 200-210. I don't know exact but there are under 1000 hours on the machine. I believe its in the low 900's. The red gas cans are to fill the gas tank to the truckmount (you see it under the fan shelf in the last pic). The box truck is diesel and the TM is unleaded gas. We do A LOT of commercial carpet cleaning, anywhere from 20k-120k, so we keep extra gas on the truck to keep going. We've had it running for 8-10 hours straight already on long commercial jobs.
