Anyone had any experience with liftgates on a fullsize pickup? I need to get one for the shop. Tommygate seems to have to most options. But Waltco, Ultron, Maxon, Eagle, Anthony, who knows? The Tommygate guy told me their steel is only 40lbs heavier than their aluminum, was surprised at that. Of course which ever dealer you talk to "theirs" is the best. Any thoughts here?
