We have 05 28C Classic. The right front corner lifts 1/2" higher than the rest of the camper. I have adjusted the cable repeatedly but stays higher. What should I look for? The camper was stored up for a year. The camper has not left the house for a year and a half., because of the cable. I am sure someone will know how to resettle the camper cables. Also how do you remove the pulley covering oak wood trim to get to oil the cables and pulleys, no indication in the manual that came with Hilo.
