Interesting. I just had time and space to crawl under the trailer. There was one pre cut opening but was at least a foot from where it needed to be. After I cut the right spot I could see the motor and hand crank
. But there wasn't and place to see if there was fluid or not. there is what looks like a screw plug but I could not tell if there was fluid or not.Going to get a small turkey baser like item to put fluid in a then when it over flows I'll know its full. Thanks for the spot to check,
