Your answer is to get one of those rubber mats and park it under the truck. It works for mine LOL.

On your question though, from what I have been reading here over the last few years, I'd say yes you need to lift it some to get the pan off. Maybe lift it with a board and bottle jack under the pan and support it with a plank across the top of the engine? Let us know how it goes.

From a forum on the AMC 6 cylinders they talk about maybe loosening some of the mains caps a bit to be able to get the top half of the seal out. The rear cap of course would have to come off regardless to get the seal out of it.
