I would start out asking about the weight. How much is the fee for delivery that he is asking? Might be worth it to save the headache of doing it yourself. And even if it doesnt weigh a ton, it looks big with a lot of surface area. It might whip around your 1500 pretty good.
I've dragged some pretty heavy trailers behind my 1500 that I really probably shouldn't have with 35s and stock brakes but nobody died and I had no accidents. You just have to be concious of what's ahead and how much your being pushed. I know my little 318 can set some serious weight into motion but stopping it is the problem.
For just one move I'd probably do it if it doesn't bottom out the leaf springs
