WOW! Thanks for all the responses, REALLY helpful. Here are my conclusions:
- I need a truck. So, I'll sell the minivan (it is a 2008 with 250K on it and was thinking about new car anyway). If I can figure out how to get my bike in the ridgeline I'll get one of those. It drives great and rated to 5000 lb towing.
- I need an enclosed trailer. I don't have inside storage, would like to protect the boats from sun, rain, damage, theft.
- Should go with the 7' wide trailer.
- Seems like I can get a 12' 6" marathon boat in the 7x12, if the V adds 2 feet.
- Do you agree?
- How tall does the interior dimension need to be if I want to get a CSH/300SSH in also without tilting on the side, or removing the windshield?
- Most of the single axle 7x12s are around 1300-1400 lbs empty. GVWR is generally 2990. This leaves about 1400-1500 in cargo. 2x Boats at 150 = 300. Three motors = 300. Carts, tools, canopy, chairs, misc.=300. Mounting racks = 100. Seems like I'd have about 1000 in equipment. Does this assumption (that a single axle would be sufficient) make sense?
