I've been looking for a new trailer for my 15' Whaler and I have a couple questions. I have it narrowed down between 2 trailers, both by Continental. The A1515 and the AS1616. The A1515 is slightly smaller (better for fitting in my garage) but has 12" tires. The AS1616 is a foot longer and has a torsion axle. The dealer has been less than par on some of my questions so I don't know how much more it would be to get 13" wheels on the A1515, but I think I definitely want 13" wheels for my trips to the east coast of FL and the keys. The price difference between the two is $300. Is it worth $300 for the torsion axle and bigger tires? I have always had leaf springs and they have always treated me well. They are cheap to replace and I would gladly pay $50 every 5 years to replace them instead of $400 for the torsion axle. What do you guys think?
