Hy,
As you say, better safe than sorry. It seems that a 1500# tow rating is about the least you can have to tow one of our 13' eggs. Even then you have to watch things, but it's doable.
There is always the possibility of a different car, although I bet you love your Jetta
I'll have to check out the tadpole - haven't seen it.
One note is that I would still want to weigh a new trailer (or see a weigh receipt) if I were anywhere close to the limit. I say this because many of our 13' eggs were said to weigh "995#" by the mfgr and that has turned out to be a bit optimistic in many real-world cases. Some mfgrs were a bit more optimistic than others.
Glad to have you aboard, in any case, and I hope you find a suitable camper
Raya
