We tow a 2005 3023 with a 2005 Dodge Grand Caravan with factory tow package with a Equalizer WDH. We live in Michigan and haven't had any problems pulling the TM on flat land. Last summer, we put the combo to the test and did a 2,600 mile trek to the outer banks of N. Carolina and then over to Cherokee, North Carolina in the Smoky MOuntains. We had no problems pulling the TM and maintained 45 mph going up 6% hills. We had one instance where we had to go down a 9% grade for 2 miles that we needed to stop and let the brakes cool. While the Dodge pulled everything OK, we were definately maxing out. We're going to do a similar trek this year and I am probably going to look at a new TV just to be safe.
Good luck!
