I pull a bumper pull horse trailer, which I thought was decent, but last year my parents bought a 34' gooseneck travel trailer and it's SO easy to pull! I really enjoy the gooseneck, but my BP gets the job done.
Oh also to note, it's dependent on what you haul with.. We haul with a new (chipped) Duramax, (my baby) and it hauls the massive camper like it's nothing.. it runs away with the bumper pull!
But I usually haul the BP with a '00 GMC diesel, 3/4 ton, and it hauls my trailer easy but it'd probably be a little harder with a gooseneck.
Goosenecks are nice, but we pull a 2H bumper pull w/dressing room with our suburban.
I agree with SBs that BPs can sway if you don't have a big enough truck. I see people pulling them with Explorers and Jeep Cherokees... just don't do that. Get something equivalent to a full size pickup.
Our suburban pulls our trailer like a champ ;) No problems with it at all. Our trailer is a 2007 Collin Arndt, extra tall, full size dressing room. Made of aluminum so it's light.
Goosenecks pull easier, back easier, turn easier, get into and out of tight spaces easier, have a place to sleep (in the GN). You can find plenty of used ones on Craigslist, although there really are trailer scams galore there, too.
