I had a situation in Havasu last fall when I needed a bearing replaced the same day so I could tow back home to PHX, one of my oil bath hubs had leaked out. Understandably, Adrenaline and Shadow were both booked up and not able to get me in the same day, so I called Frank's trailers. He was able to get me in and convert all of my hubs from oil bath to grease the same day at a fair price.
Just took delivery of a used trailer, arrived with NO brakes...looks like a total redo on the actuator, lines, calipers and rotors.
FWIW - I gave written instructions to the marina that did the PPI and requested "verify operation of trailer brakes". All 4 rotors were very rusty and obviously hadn't been used in a while. They totally dropped the ball.
