I will tow my 1993 Nissan 240SX with a 2005 Toyota Sienna FWD from my home to race track (about 300 miles) about once a month. The max tow capacity of Sienna is 3500lbs and 240SX is 2700lbs. The tow dolly should be around 500lbs.

Total tow should be 2700+500 = 3200lbs. I think it should be fine with 6 extra rims/tires in the back trunk of Sienna.

I know getting a pickup truck and a trailer is my best solution, but I don't have enough garage space for storing a trailer. So, tow dolly is my best option right now.

I am very new to towing/tow dolly. Could you confirm these are all I need for towing my 240SX with Sienna?

Did I miss anything? Will my setup work? Any other suggestions?

Another question that I have is the hitch pin? Do I need it?

Thanks! :)

you are right at the max towing capacity.

do not know the miles on your van, but you will want to watch transmission, I would get it flushed at 30K then again at 60K if you are towing at this level.

stopping is the main problem: does the tow dolly have some type of brake, I would try to get one with brakes.

I tow a travel trailer and I can pull it find, but when some so/in/so pulls out in front of you then stops to make a left turn you must be able to stop the load in a reasonable distance.

with no trailer brakes its almost like the load starts pushing you faster the harder you push the brake petal.

Just a heads up from someone who has been there!!!!
