I will be buying my first trailer in a few short months and my barn owner said that bumper pulls are great. They are easier to drive, back up, and park. Good luck with your search.
i disagree with your barn owner! i've ALWAYS found goosenecks to be easier to pull and back. let's put it this way: any kind of gooseneck, i'm a backing FOOL. i'll get it where you want it, to a T. i've even gotten pretty good at backing the big truck trailers (48 and 53' flatbeds) into the shop at work.
bumper pulls still get me in trouble sometimes. the biggest problem is it's a lot easier to jackknife a bp. seems that it takes a lot more effort to learn to back one over a gooseneck.
these are a few photos of my trailer at my mother in law's house near albany ny. she lives right off a main road, and i DID have to pull into the neighbor's yard across the road but that's because i couldn't block traffic for long. one shot hit, i was pretty proud of myself on this one!
now, what to pull it with? disregard brands. pick whichever one you want, all have advantages and disadvantages. then configure whatever brand you choose into an appropriate 1/2 or 3/4 ton. doesn't sound like you'll do ANYTHING that'd warrant a 1 ton. that trailer of mine is a 20' and i wouldn't hesitate to load 4 horses in it and pull it back up north to ny if there was NEED for it. my 3/4 would do it and ask for more. hell, we hauled 2 horses and a bunch of household items down here last year.
i see you're from ny as well. i'm from down here in ks and it's generally flatter, but i do see a fair number of 16' goosenecks pulled by half tons and i don't know that I would, however that's just me. point is i think some people underestimate a half ton. but if in doubt, go a bit bigger and get a 3/4 ton.
like i say, i'm sold on goosenecks, but as mentioned before, the NICE thing about bp trailers is the fact that any pickup with a hitch can hook on and pull it. it's why once our BP gets finished being worked over by the high school shop kids in town it'll come down here again so we have a way for the wife to move critters around if need be.
