Menards sells the pit boss utensils right in the store. Mine was a floor model and is missing the grease cup. Just bought it 2 days ago so I'm excited to try hibachi grilling!
I'm about 5'10. From the floor to the cooking surface is about 35.5" inches. If you use the pitboss utensils, they have a longer reach to them that may help you.
I'm easily 50+ cooks in, and i don't have any issues. I mean you get a bit of sticky bacon, but otherwise has been great. Scraper tool picks up anything caked on with a pass or two. Although i have not done anything with a sauce to it, and i read on the FB groups, that can be an issue, depending how high you have the heat at.
