Trailer hitch on WRX... good or bad?

I have a hitch since fall 02. People have already talked about weight
and loading the engine. Some other issues are AFR and heat. The AFR
leans out when driving for a while on flat steady speed. Be a little
careful riding on flat ground for a while and hit a steep hill. If you
know a hill is coming up, do some small pulls beforehand. If you have
the stock uppipe and TBE, it makes the exhaust gas much hotter than a
non-catted uppipe and a TBE with a high flow cats. There has been
documentation the stock exhaust temps (a few inches from the heads)
commonly runs 150 to 300 degrees hotter. Once again loading the
engine a few times before hitting a hill will help.
