Might want to check the inspection rules for trailers with vs without brakes. Brakes on the trailer could be a nice thing but could be far more costly then just upgrading the brakes on your van. I tow an enclosed trailer, single axle and no brakes and the brakes on my SUV (Xterra) do just fine. I drive a little slower and give myself more space for the added measure of comfort.
I added the E channels to mine, a must do as it makes it so easy to strap things down.
