Drive Guys,

I have a 2006 Toyota Sienna LE, which I use to haul model trains to train sales around the country. I estimate the weight of the load is around 1,000 pounds, which is well within the load weight limit for the vehicle.

However, I can see that the rear of the vehicle is about two inches lower with this load, and at night oncoming drivers are constantly flashing their lights at me, so I think I need to install heavier duty springs to level the loaded van. (I had them on an earlier Olds Silhouette and they worked great!)
