We loved both our mega cabs we had. First a 2006 that had horrible turning radius and then the 2012 Mega 2500 that turned outstanding and was just an all amazing truck. From taking our kids to just the guys taking it out for fishing trips it's amazing. Recline the rear seats store stuff back there. What more could you ask for.
We never used the slider hitch with our 40' 5er but yes parking it was not anywhere near the store entrance. And taking up 1.5 parking spots was mandatory.
But they are beautiful and great ride.
But the truck was also not a daily driver. It was stored in our garage until camping time or special outings.
But the long trips were great in it. Our kids never complained about room or the ride even when our dogs came with us. Always enough room.
We just purchased a 2016 Ram bighorn crew cab 3500. Kids already complaining the seats don't recline for them. But we couldn't swing cash for a Mega and a Cummins in a 3500.
My only complaint about the Mega is dodge removed the "Mega" emblem from the truck.
I think the emblem was a badge of honor. The look what I got factor.
