that camper was a brand new purchase at Coos bay I then went straight to Alaska for 2 full months in Nov, Dec,Jan. returned to NY across Canada I year later the Jack's were like that !!!!!! I live in the foothills of the ADK mts and we get a fairly large number of snow storms BUT this was caused by poor to non existent quality control which is the norm for Crapi Hapi jack, that was then and it appears nothing really has changed, when it concerns quality /quality control they find ways to cheapen mfg costs while charging the end customer more !!!!! Thet were repaired by Bigfoot not Crapi Jack non existent customer support
ps I have a pile of worthless Crappies in my cellar left from earlier replacements , 4new spare motors also have many pix of hj I cut apart to examine causes of jams & problems ect
