Towing vehicle - Event Date: 12 Oct 2016 - 25 Dec 2016

Hello Everyone:

Since your Sienna does not have a factory tow package, but an add-on hitch instead, there are a couple of things to note.

First, the hitch may be rated at 4500 lbs, but the vehicle is still rated at 3500 lbs. That is your limit. A heavier-duty hitch does not increase the vehicle's tow capacity. Second, since it is an aftermarket hitch, you should also get a transmission cooler installed. Third, while not strictly necessary, a heavy-duty alternator would not be bad to install either. Fourth, with this vehicle, a weight-transfer hitch with stability is going to be essential. One of these three should be purchased: Equal-i-zer 4-way stabilization hitch; Fastway E-2 hitch; or Andersen No-Sway weight distribution hitch. There are others also, but make sure it combines sway control with weight transfer.

One other thing that we have found that helps. We added an AeroPlus wind deflector from PurpleLine USA. Another one is the AeroShield by Icon. These improve the airflow between the tow vehicle and trailer. Our experience is that it increases our mileage significantly. This is optional though.

I don't think the Sienna's engine is turbocharged. You will find it works okay on flat land and hills. However, it would probably struggle at higher elevations and mountains. This is not to say it won't work. Just understand that you won't be going up 10% inclines at normal highway speed.

The R-Pod comes with electrical brakes. Unless your tow vehicle comes with a built-in trailer brake controller like some of the trucks, you will definitely need to purchase and install a controller. Some people use the Tekonsha Prodigy P3 controller. I chose the Hopkins InSIGHT Flex-Mount trailer brake controller as it gave me better options on where to mount the components. I have been very pleased with the installation.

As for larger radiator and fan, I can't answer than one. What I did is to get an OBDII Scan Tool. I also got a cord to allow flexibility in plugging in and placement of it, but that is optional. I use the Torque Android app on my phone to monitor engine and transmission temperature and other performance parameters. I would recommend getting an OBDII device and then determining whether spending the money on a new radiator and fan are warranted.

I installed a Husky Quest brake controller. Whichever controller you choose, I'd highly advise one with proportional braking: it measures your rate of deceleration and applies an appropriate amount of braking pressure.

StephenH,
     Thanks for the link to the scanner, I've been wanting one but too many to choose from. Good to see one that worked out for someone here, just ordered it. I have a light duty TV, 2016 Santa Fe and have been wanting to be able do monitor temps. I have a spare Android phone which will do fine as a permanent display. Love your mods by the way.

Thanks
