Mobile or shop bay
Three of the 14 are mobile techs, meaning they roll up to your campsite, driveway or storage lot. That saves you a tow when the issue is a fuel pump, a clogged carb or a control board. For bigger jobs like a stator or a full generator swap, a shop with a lift and parts on the shelf usually wins. JoCoPro LLC and Wolf's Mobile RV Repairs both advertise emergency and weekend availability, so they are worth a call when you are stuck. Ask upfront whether the tech carries common Onan parts or has to order them. If your generator runs but surges or dies under load, describe that exactly when you book. It points the tech toward fuel delivery rather than the ignition side, and it may change who takes the job.
Warranty and parts
Eight of the 14 shops here do warranty work, which is more than half. If your generator is under an extended service plan or a manufacturer warranty, get pre-approval before anyone touches it. A shop can call the plan administrator with you, but the approval is yours to chase and it saves arguments later. Camping World in Roscoe and Colman's RV both list warranty and parts, and Colman's is certified. Kendall County Repair also stocks parts. Ask whether the part is in stock before you drive an hour, because a generator sitting in a bay waiting on a fuel filter helps nobody.
The rest of the rig
Almost every shop that fixes generators here also fixes something else. All 14 list fridge and awning work, 12 handle roofs and 9 do slide-outs. That is useful when a trip turns into a list: the generator won't start, the awning won't retract and the roof has a soft spot. Book one stop for all three instead of three appointments. Nine of the shops winterize, so if you are closing out the season, ask them to check the generator exercise schedule while the rig is in. A generator that sits unused for months is the one most likely to need a carburetor cleaning in spring.
