That was MY caravan... don't laugh at! I could do it, I just needed a better run at it, that's all!!!
Seriously, you'll be fine. I've towed with my P5, so far only about 500 lbs including trailer... and it's worked great. I do plan on getting a boat at some point, which will weigh a bit more, but I will look into trailer brakes if it's over 1,000 lbs. I don't want the boat pushing me around if I need to stop. At 500 lbs, I didn't really notice any more braking effort.
