I would like to carry two fiberglass kayaks on my 1993 Toyota Previa.

Right now I carry the kayaks using a Yakima system on my F150
Supercrew but I would like to bring the van into the picture to take
advantage of its better fuel economy.

I would stick with a Yakima or Thule system. Strong, versatile,
removable. I can't really think of any vehicle where the factory
installed racks would be suitable for 100lbs worth of boats - Except
for maybe a Nissan Xterra.

Cheers,
