Hello all. Proud new owner of a BHTR 39MB. It has the Lippart level up on touch system. I have never used a level up system before. I have read the manuals and understand hydraulics. After I disconnect the truck, pull it away and do the auto level, all is fine. But when I hit the hitch height button the middle jacks come up all the way. The rear drivers side jack comes up about 3 inchs and stops. The rear passenger jack stays on the ground. The trailer then raises to the auto hitch height. I am concerned with having the rear jacks staying down and the trailer goes high on the front that it is putting alot of stress on rear jacks. Can anyone offer any advice. Thanks in advance.
