too much trailer for your 3.6 v-6 Acadia!
my 23SS weighs around 5000lbs. loaded for camping and that's just for two of us.
you have to subtract the weight of anything in the Acadia, other than a 150lb. driver, from the 5000lbs.
that includes any other passengers, cargo and WDH.
my '07 23SS is 6" narrower and weighed 4500lbs. from the factory, with the standard "options" that most trailers have.
you need to find something else to tow it with or get a smaller trailer.
