WHATS IT REALLY WEIGH?

i am thinking about keeping her as a trailer queen. the hull is just so dam clean i hate to paint it. i have a toyota minivan with a 3500 lb tow package. 86 v 20 with a v8 i/o and hardtop. the ramp is about a half mile from my house if i take the scenic route. anybody forsee any trouble with this setup? should i have any problems getting her back up the ramp once i load her up? i have absolutely never pulled a trailer before so i dont know the first thing about it. the van doesnt even have 1000 miles on it so i dont want to screw that up. she sits on a two axle trailer... whats this rig really weigh?
