I tow with my Jeep Cherokee (GVW 3800lbs). The aluminum trailer and my heavier 911 may be a total of 3500lbs. I load as much of the heavy stuff into the Jeep as I can. The Jeep has enough power, but the weight of the thing can sometimes make it nervy when towing. Still, I haven't had any problems. Trailer weight balance/distribution can make a big difference in handling. Stay alert and make sure you know what the rig is going to do if you have to react quickly. Test the handling before you go too far. Change the balance if you need to.
I couldn't go cross country over the Rockies, but it's fine for the 800 ft above sea level average midwest terrain
