I've been pulling a Kwik Kamp with my 2001 I/S for a number of years. When I got it I set it up on bathroom scales and got the following measurments. (trailer empty but with a full small propane bottle, spare tire and empty cooler.)
Total Wt = 479 Lbs
Left wheel - 208 lbs
Rigth wheel - 206 lbs
Tounge = 65lbs
I've loaded it up as much as 660 lbs with a tounge wt of 98 lbs. (Darkside)
Never really had any problems except it does not like to pass gas stations. Typically get about 24 MPG but once on I10 at 80MPH with a 20 Kt headwind I got 18 MPG.
I've only ridden it solo when pulling the trailer but I did loan it to a buddy once who put his wife on it and did a 1000 mile trip including 10,000 ft mountain passes. He never complained.
YMMV
Planning a couple of longer trips in a few weeks and was wondering about trailering my gear. I have pulled a trailer behind the phat gurl (99 std) for several years but never wanted to take as much gear as now. I know about the 60% weight in front of the axle, etc. What I do not know is about how much weight (including the weight of the trailer) can the ol' girl handle safely. Can't seem to find specs anywhere. Any thoughts would be greatly appreciated. Larry
