I traded an almost new EZLoader on a Roadrunner model 4500 Long Bunk in 2006. It has 12 ft bunks, load guides, 7 ft tongue and flush kit. The EZLoader was a piece of junk (rant on this trailer on this site a couple of years ago)and just never fit the boat right.Had issues with both LED taillights filling with water and it rattled when towing. Of course I took a loss on the EZLoader but to me it was worth getting rid of it.
I am very pleased with the Roadrunner - done a couple of tows to Campbell River - tows like a dream with my Ford F-150 with a small V8. Mine came with Goodyear Marathon tires - manufactured in New Zealand of all places.
The only complaint I have with the Roadrunner was the cheesy Chinese knock-off bearing protectors - circlips and springs corroded. I removed them and ordered a set of SS Bearing-Buddies from Puerto Rico.
I recommend Roadrunner trailers- quality built in Canada of course!
