I purchased a 16' Boston Whaler on a galvanized trailer. After I got the rig home and the wheels off all I saw was rust on the hubs , axel and springs. So I replaced the axel, hubs w/new bearings, new springs and new wheels and new spare. All this in preparation to tow the rig to florida from Delaware. Now to my question: The tires that were on the trailer and the new ones are 13" and each is rated for 1350 lbs load @50 psi times 2 = 2700 lbs. the axel ,hubs and springs are rated for over 3000 lbs. I had the rig weighed at a local feed mill and to my surprise the rig weighes 2700 lbs stripped as much as possible. Am I crazy for planning to tow the rig 850 miles, most of which would be at 60 mph on I-95?. I have towed the rig for about 20 miles at 50-60 mph to be sure it towed well which it did. The hubs were cool but the tires were slightly warm but didn't get hot.
