YS1500 Mobility

Hi Guys,
Tossing up between the YS640 or the 1500. The only thing I am stuck on at this moment is getting the YS1500 around to places.
I see it is close to 300Kgs, I have a ute and also a Dirt Bike Trailer, but I dont know if me and my missus can pull 300Kg up a ramp.
How do you guys transport them? Can two people pull it around easy.
On the YS640 capacity, on an average how many can I cook for on that? Say Brisket and ribs.
Want to cook for some local shows, weddings.
