Hello Conner and welcome to the DOW.
What city ?
There is a chance I may have driven through there . I have ran on wood through AL , AZ, AR, CA, CO, FL, GA, IL, IN,KS, KY,LA,MI,MS,MO,NE,NV,NM,NC,OK,PA,SC,TN, TX, UT, VA, WV, WI, and WY
I have driven somewhere between 200K and 400K miles . Lot of the miles where unnecessary but fun
I have run into road blocks several times for drivers license and insurance checks but none of the officers have ask about the apparatus in the the bed of the truck. However I was stopped by an Alabama State trooper but he didn’t question anything about the truck but he did give me a speeding ticket. ( 75 mph in a 55 zone ) Until this day he doesn’t know he gave the first woodgas speeding ticket in the US
Driving on the countrfy roads are more enjoyable than the city but that is true with me gasoline or wood.
If the gasifier is built right there should be no smoke to get any attention. With a little practice you can learn to run your gasifier down to where there will be no smoke even when refueling.
Also there is another trick of driving in tight areas if you have an auto trans . Learn to do the braking with your left foot so you can hold the throttle smooth .
I hardly ever get any attention with the truck .Below is a pick taken just an hour ago at Walmart. Grown men walking within a couple of feet of the truck and not even notice .
