I could certainly be wrong here, but the way I understand it, is that for the same weight GN vs BP, you would normally have more weight on the truck for the GN since you typically have 15%-25% tongue weight, whereas the Bumper Pull would typically have 10%-15% tongue weight. This would leave more weight available to put "stuff" in the bed.
I know a lot of you are die hard GN fans, and like I said I'm not arguing that a bumper pull is better, I'm just surprised that I can pull more with the bumper pull that's all, regardless of the fact that the GN would tow "better".
By the way, where do you guys with the goosenecks put all your other "stuff"? I often carry my brush saw (weed wacker style), gas powered pole saw, two chainsaws with my "saw bag", log peavey and a few other tools. Do you still put that in the bed with the GN? I imagine you can still fit some things back there right?
Mike,
It's a good point about getting a longer GN and I'm not ruling it out, but along with extra weight of the longer gooseneck, now I have even less payload, and even more weight on the truck.
Maybe I'm looking at this all wrong, but I don't see anyway that an equivalent sized GN can carry more than an equivalent sized BP???

I can definitely see why it would carry it better though.
