I've had my sunfish for 20+ years, but between having a pickup and living on the water, I never needed a trailer until recently. I bought one at Academy that was designed for a flatboat and altered it to fit my boat. I ended up with 8" wheels because the trailer with 12" wheels was just huge. My question is if I want to pull my boat about 5 hours on the interstate, are the 8" wheels going to be a problem?
