Re: Bayliner 88 capri 15' Van tow?
Take this reply for what it's worth, as I am not talking about legality, safety, or anything else like that, but as for what it will pull....
I grew up on a farm and I used to pull 60-70,000+ pound double cotton trailers (weighed, so I know this is accurate) from the fields to the gin with a regular 4X4 Chevy Pickup. It took a little technique, and if anybody pulled out in front of me, they were in trouble, as braking was a bit compromised, but the truck would pull all harvesting season long, year after year, after year with no problems.
That said, pulling on a public road with an overweight trailer is not something I would be comfortable with. When you are pulling, people will do the dumbest things imaginable in front of you. I have a 2000 Toyota LandCruiser with a 6,500 towing rating capacity, and I pull a '99 Sea Ray 190 BowRider with a tandem axle trailer (guessing no more than 4,500 lbs. fully fueled and ready for the water), and while it tows fine, no problems, I still wonder how it would do if I were ever to take it a really LONG distance. I think it entirely depends on how far you are towing, the type of roads you are towing on, and how comfortable you are towing with a decent amount of weight. But, as for your situation, assuming your weights and ratings are correct, I would think that your vehicle would pull it ok. Just depends on your specific towing situation.
