I am looking at the purchase of a new 2019 Aliner Expedition. I am 62 and have back issues and hope to use this camper for 20 more years. It does NOT have the power lift system. The dealer s saying there have been issues with the power lift and they don't order them that way anymore. Dealer also says that in the 2019 and 2020's the springs and manual lift assist was altered to make them easier to lift. I'm going to look at this Saturday and will put it up and down several times myself. But I want to hear what you folks have to say?
