Hello fellow Toyota owner. This topic sounds all to familiar as I did extensive research before purchasing my RAV4. I knew I was getting a PUP, so the tow package was a must. I was dismayed by the lack of knowledge at the dealership on this topic. I had picked out a RAV that I liked and asked about towing. Without hesitation, I was told any RAV could tow 3500lbs. WRONG, it HAS to have the tow package.
I ended up with the perfect RAV and tow a Fleetwood Yuma which is rated fully loaded at about 2,400 lbs. Seriously, it's hard to tell it's even there. The biggest thing I notice is the gas mileage. It goes from a great 27 MPG to about 15. UGH, but the Fort is worth it. Lastly, I only tow in Florida and the only ice, slush, cold stuff I encounter is if someone dumps a snow cone or slushy out the window of their car.
I believe the weight the dealership quoted you is for EVERYTHING, PUP, people, equipment, food, water, air, gas, paper clips, maps, etc, etc. It sounds like the total max weight the van can handle. Don't get close to this number, it's not a good idea.
So, I did some researching on the Sienna and this is what I found.
MAX TOWING IS 3500 LB WITH TOW PACKAGE
Standard is 2000 LB
The good news is, depending on your year Sienna, the tow package was standard equipment up until 2008. The tow package includes engine cooler, transmission cooler and wiring harness. Have you looked for your wire harness at the back of the van? It probably will be where the jack handle is at the back, drivers side of the van, stowed away in a compartment. This would confirm that you do have the tow package. Also, the radiator is suppose to be larger than a standard one.
I also found this info from one of the many Sienna forums.
The summary of those discussions are presented below. It is based on Sienna's electronic brochures and recollections of other members, who read those disussions, spoke to dealers and made their purchases.
Towing capacity
Model year . . . U.S.A . . . Canada . . .
2004-2007 3500lb 3500lb/1587 kg
2008-2009 1200lb 3500lb/1587 kg
I had U-Haul put the hitch on for me along with the brake contoller. A visit to them also might help find out exactly what your van has already installed for towing. I found out that our local U haul does the hitch work for all the local dealers. So, be sure to research a little. Some dealership say they can install the hitch and then send it out to be done.
If you have the tow package, you should be fine with the PUP your thinking of. And yes, it's a good price.
Best of luck with your project.
