To figure out if your 2009 Pontiac Montana SV6 has the short or long wheel base would be to measure from the center of the rear wheel to the center of the front wheel, or you can call your local GM dealer with your VIN and they should be able to look it up for you.
If you get a measurement of 113" then you have the short wheel base, and if you get a measurement of 121" then you have the long wheel base.
With that said the Draw-Tite Trailer Hitch # 75278 you were looking at fits both the... view full answer...
We do have the Curt multi fit hitch part # C13704 that has a 5,000 lb towing capacity and can fit RV frames that are between 22 and 66 inches apart. You'd have to make sure your frame dimensions are compatible and that your trailer when loaded would be less than 5,000 lbs. view full answer...
I believe I have what you need. Since you said you have a shaft size of 1-1/4 I am assuming you are referring to the spindle. The Brake Mounting Flange # 4-34 is designed to work on spindles that are 1-1/4 inches in diameter and should work for you.
The description says that this flange works on 1-3/4 inch axles with 1-1/4 inch spindles.
With this brake mounting flange you will need to use a 7 inch brake assembly. For a left hand brake assembly you could get a Dexter Brake Assembly #... view full answer...
For your 2008 Pontiac Montana SV6 with raised side rails you would want the Thule Roof Rack part # MPG216 as it has been confirmed as a fit. view full answer...
The roof racks made for the 2008 Pontiac Montana SV6 were designed with raised rails in mind since most of the cars of this model came with raised rails. Since the Pontiac Montana was discontinued and had limited production from 2007-2009 its possible you have a different from usual version.
If you can confirm that there are no rails up there or even holes or possible fixed mounting points, I have two more creative solutions.
The first, is the SeaSucker Monkey Bars Roof Rack # 298-SX6000B.... view full answer...
For the lowest cost roof rack option that will fit both your 2005 Pontiac Montana and 2010 Subaru Forester, both with side rails, I recommend using Inno feet # INFR with 50 inch bars # INB127. This system will be fast and easy to install or remove and it is compatible with the Yakima HullRaiser kayak carrier Y04039. I know it isn't one of the ones you mentioned but based on limiting cost it is the best option.
But using these carriers will limit you to 2 kayaks at most because there just... view full answer...
To add a 7-Way trailer connector to your 2009 Pontiac Montana with a 4-Way you will need # 37185. Your 4-Way will plug into this adapter's mating 4-Way. You will need to ground the white wire to the van frame. This adapter has both a 4- and 7-Way connector so you will retain the use of the 4-Way.
The remaining wires on the adapter are blue for electric brakes, purple for reverse lights, and black for 12 volt power. You already mentioned not using the trailer brakes so the blue wire can... view full answer...
The Roadmaster High-Low adapter # RM-076 is designed for use with tow bars only, when flat towing a vehicle behind a motor home. They are not meant for use for any other application.
Some adapters and extenders can reduce the tongue weight capacity of a trailer hitch. Others do not. It depends on the adapter and the trailer hitch Class.
What I recommend is the Curt multipurpose ball mount # D210. This will provide extra height and it will not reduce the tongue weight capacity of the trailer... view full answer...
