Introduce yourself

Welcome and Congratulations! I hope you have many fun adventures and make many great memories with your RP180. We have a 2016 RP179 and are currently towing with a 2010 Nissan Frontier. Since you say your 4-Runner has a 5,000 lb capacity, I am guessing it comes with a factory tow package. You will need a brake controller as well. We have the Hopkins In-SIGHT Flex-Mount controller and have been very happy with it.

WDH/sway control:

If you are getting WDH, make sure it has sway control built in. That way, you don't need to mess with a separate sway bar and its complications.

A good one would be an Andersen No-Sway hitch. It is probably the lightest of the WDH hitches with sway control. All the others use a heavy hitch head and bars. If weight is important to you, check out the Andersen hitch.

We currently use a Hensley Cub hitch. It and the ProPride hitch which is similar are the Cadillac of hitches--quite expensive unless you can find a used one.. It is easier in that the main part of the hitch stays attached to the trailer and the part that attaches to the vehicle is very much lighter although hitching up can be challenging, more so than the demo on the web site where things are perfectly lined up.

We used to use an Equal-i-zer 4-point sway control hitch. The head is heavy, but it was pretty effective. Similar to it is the E2 hitch which is a 2 point sway control hitch. The E2 is less expensive, but many have used it and found it to be adequate. There are other brands also. Just make sure that you buy one that is suited to the weight (overall and tongue) weight of the RPod. For example, the Equal-i-zer 6000/600 (6000 lb capacity, 600 lb tongue weight capacity) which is the one the dealer installed when we bought our RPod.

That is my $.02 worth. I'm sure others will also give their input. I wish you well.

Unlike StephenH, I prefer separate sway control from the wdh. That allows me to adjust the level of sway resistance independently from the amount of weight distribution. There is a school of thought that a lot of sway resistance is undesirable on wet or loose road surfaces because it could cause the tow vehicle rear tires to break loose, so in those conditions and on very winding roads I lower the friction in the sway control arms. The all in one systems don't allow for that. Just my preference. 

Welcome! Now that you have it fixed, I hope you have many fun adventures and make many great memories doing so with your RPod.

Was it the AC that fell or only the inside shroud for the AC? If the whole unit came through the roof, that would really be bad.
