I had one on my f250 for about 6 years before I sold the truck. It was great. Picked up way more things solo than you'd think possible. Gave me an extra 6ish inches in the bed, which means you can fit 10ft sticks at an angle fully in the bed. I traded a 350 crankshaft for it, gate was too wide so I cut the whole thing in half and welded it back together after taking about 5 inches out. Also since I was running 2 awg cables to the back for the gate I added a jumper quick connect at the tailgate which was very useful at times.
Downsides - brought home too much "if you can get it out of here its yours" junk, even more people ask for help moving. Finally it's really hard to find a bed cover solution that works with a lift gate. I found a bed cap and was going to bend a piece of sheet to cover the gate, but the truck developed some major compression issues so I dumped it when the repair bills started really rolling in
