Hi, we just bought a 13' scamp weighs 950lbs. Has trailer brakes, subaru forester seems to be in good shape never given us issues, got it inspected by our mechanic and some general maintenance done. But we live in CO and will be in the mountains towing. Likely no more than 3-4k miles per year towing. Wondering if we're pushing it with this vehicle or not? Only need to it to last another 2 years so not worried about long term effects, just don't want to break down on the side of the road.
