The frame and brakes should be up to the task; you may find the motor a bit weak pulling 3K around, especially if you're going over the passes. If you're staying on the (relatively) flat terrain in E. WA you should be OK. It certainly will do it, although you'll have slow going up long grades/hills.
I once towed my present '90 LS Troop 180 miles back from Bellingham, on a car tow dolly, with my trusty old '90 2.8 Troop. It handled the load OK, but definitely don't recommend towing that much weight on a regular basis!
Probably close to 4500 lbs total but the 2.8 never whimpered. 55 and 4th max, though. Likely a good idea for your towing also; never tow that much weight in 5th; the gears in 4th are stronger for towing. Make sure your tranny oil is in good condition and at the proper level. At that weight level it's also extremely important to have the cooling system up to snuff; old hoses, clogged radiator, bad clutch fan or thermostat will spell Instant Meltdown if occurring while towing. Especially in E. WA heat, although there's not much of that to worry about now, is there!
