I am studying on doing this too. I have the wife's 4runner I can borrow, to tow with but the main reason is because I see gas going high...
Once it gets beyond 3 bucks a gallon it starts really making a dent. My 97 saturn sc2 is rated at 1000 pounds also, but really that is enough.
I already have a 5x10 wire mesh trailer and I would guess it weighs somewhere around 500-550 pounds, so what I am going to try and do
is just use it, and make sure I only haul one trike, or maybe two dirtbikes. The only issue I see is it would be easy to fry the clutch.
On big hills I would keep it out of fifth gear for sure. I can get near 50mpg on the interstate with my car, so I don't see any issue getting at
least 30 towing. That kind of mileage would pay for the hitch pretty quick, which is around 130 or 140 dollars. The site I've been looking at
for stuff was e-trailer.com and they have plenty options for hitches, wiring kits, adapters from 1" to 2" etc etc. I thought about going with
one of those tractor supply trailers the 4x6 ones, but really at what they cost just to save 150 pounds or something it's really not worth it.
Some of my dirtbikes are longer than the 3 wheelers too, so I think at 6 feet it's going to be sketchy and not quite long enough. A 4x7 or
4x8 would work much better for sure
