RV Works Cajun Fryer – they are pricy but the design of it allows one to change the oil infrequently.
This is what I have used for years. Actually have 2 of the 3 basket models as we used to do a lot of fish fry events for charities. They are frying machines.
RV Works does have a variety of sizes, from ones for the home/cabin to ones that could be used for a business.
