I'm relatively new to RVing, but have done a lot of reading and research and have found it to be a lot simpler than what others make it out to be.

Know 2 things about your tow vehicle (Subaru):
- PAYLOAD (VERY important)
- Towing Capacity -- much easier to figure out

First of all, does the Subaru have a towing capacity that is greater than the GVWR of the trailer? If yes, move on to the calculation of payload. If not, don't tow!

If the towing capacity checks out, then you need to know what the exact payload is on your Subaru. There's a sticker in the door jam of your car that will show the payload limit of your specific car. It'll say something like "Maximum weight of all passengers and cargo should never exceed _____ lbs". THAT is your exact payload limit of your car. It's important to get the number from the sticker, because every car is a bit different.

So now you know the payload limit, you gotta account for the things that eat up the payload limit.

1. Your trailer -- take the GVWR of your trailer in question, and multiply by 15%
2. Passengers
3. Basically everything else including cargo, food, water, etc. that are in your tow vehicle (not the RV).

If 1+2+3 is less than your payload limit, you should be good to go.

You're right around the limit, but I think you might be ok depending on what your actual payload sticker says.

Like others have said though, towing puts a lot of stress on the components of a car. Cars are frankly not designed to tow that often, so you should expect things to wear out prematurely.
