Goose is less money and for what your doing it should work good for you. I have a 48' Halmark with living quaters in the front and it's a goose set up.You can buy 2 types...one is mounted in the floor of the truck and the ball folds down in the floor.Nice thing with this set up is you have full use of the box.The other set up has cross rail bolted cross the floor.It''s the same setup has a 5th. wheel.Some people think they roll alittle because it's a ball but if you think of it that may be a good thing. I don't find it does .For what it's worth, I've been pulling trailers for over 30 years.
