I tow a race trailer (open) and the whole setup weighs almost 5K. As to your question, it depends on how much tongue weight you are putting on it. The rule of thumb is 10% of your total weight on the tongue. The auto height-control is rated for up to 700lbs which should be plenty. If you haven't loaded your TT correctly and you have too much on the tongue, you will bypass the height control. Get your trailer weighed somewhere with all your stuff in it to figure out where you are on totals. They sell a tongue scale that you can use to check your weight. Equalizing hitch takes weight off the tongue so you should be OK to use of of them instead. I tow a 16foot long box trailer (2000lbs) with my Lotus Elan vintage racer (1400lbs) and use an equalizer hitch. Tongue weight varies from about 300-375, depending on how many spares and tools I carry. My equalizer torsion bars have a length of chain on the trailer end and you can ajust the amount of preload on the bars. On the 470 I'm using 5 links of pre-load instead of the 6 on my old Dodge Ram, to get a level ride without any sound from the suspension compressor when I raise the trailer jack putting the load on the vehicle.

My '06 470 had the trailer brake pigtail in the glovebox, but, I ordered the factory towing pkg.. I installed an Oddessy controller by splicing the Oddessy loom to the pig tail. Then i made a removable mount that replaces the Fuse Box cover when I need to tow. Works great and is completely reversable (no holes drilled in the dash) My '06 470 had the trailer brake pigtail in the glovebox, but, I ordered the factory towing pkg..

I also use a Tekonsha Prodigy. I mounted it using the connector harness supplied with the truck, and mounted it on the bottom of the dash near the door. It's out of the way but can be easily seen from driving position, and easy to reach if needed. The plug for the connector took some searching for. It was hidden above a wiring harness. I use a Valley Odessey Controller and made a clamping bracket out of some aluminium bar stock and rubber feet that installs in place of the fuse block cover. It installs in about 5 min, most of the time being spent upside down on the floor plugging in the wiring. The back piece has 1/2" tall rubber feet to clear the rim of the opening and the front piece has flat rubber and felt to prevent marring the finish. Nice thing is no holes in dash and it's removable, but, you'll need to remove it to get to the fuses (a screwdriver and 2 min..) I can send pictures if you wish.
