sounds like he is getting the treatment I got when I started looking for a basket. Yakima sold the rights of the VX to Isuzu, so nothing they have should fit...you should have to go directly through Isuzu to get all accessories for the VX. So Yakima doesn't advertise anything for the VX.
When I went to my local Bike Shop and tried to get a Yakima Load Warrior....the people kept asking..."What year make and model"...and "Oh it's not in any of Yakima's catalogs, it won't fit"...."We don't want to order it if it won't fit" etc.......
all you need to do is say "I want a Load Warrior, Extension, and 2 bags of locks for it" ...........THERE DONE.......
I use mine for my 32" spare.....can carry another one if done right....haualed furniture(Desks, shelves, entertainement centers, beds, mattresses, etc), spare rims, boxes when moving, my Big Powderhound holds 4 snowboards or 8 pairs of skiis, and just about anything else you could stick up there..... and with something cushiony and the right girl........... ;Dp; it can be very useful..............
