My Wife and I are looking to buy a travel trailer to take on 4x4 weekends and shortish vacations. We're planning on using our 91 Amigo to pull it, and we're looking at trailers that weight 3,000lbs or less (loaded, ready to roll). I would like to see what other Isuzu people think of my upping the tow rating on our 91 Amigo. Here's how 1st gen Vs. 2nd gen shapes up:

(I don't know why the 'code' tag is showing up, but at least the table is readable now)

Code
                    1991 Amigo     Modified Amigo    2000 Amigo 
Horse power    120 @ 4600       200 @ 5200      205 @ 5400 
 Torque          146 @ 2600       225 @ 4000      214 @ 3000 
 Wheelbase          91.7                95-96              96.9" 
 Vehicle weight     3615               3700                3908
 Tow rating         2000             ????????              4500


Is the frame of the 2nd gen stronger? I can upgrade our rear brakes, and will be putting in a different front axle, probably a D44 so we'll have better brakes than stock. We're also on 35" tires with a rear SOA. I can also install air bags if necessary to help out the springs (The bumper I put on is around #80 by itself).

I know it towed our current trailer, around 1,800lbs with the 4cyl, and 35s without any problems (other than power). No sway, and no braking problems (electric trailer brakes). Thoughts, other than "Stick to the stock 2K limit and be safe", would be welcomed and apreciated.
