Picked up a year old Q on Craigslist for $75. We use it when camping. I noticed the current models have a thermometer in the lid, this one doesn't. Heading to Wally World to see the thermo location on the lid and probe length. Bet I can find a suitable solution. Photos to follow.
Dirt easy. Drilled 1/8" pilot hole and then a hole slightly larger than the thermo stem. Tighten the wingnut and now I don't have to put my beverage down to know when the grill is heating or out of gas.
