I am writting this from Bellingham,WA. We made it with no major damage. The bias ply tires wore badly from the weight. The Radial replacements did not. Plus, they are much nicer running and do not hobby horse on concreat roads like the bias ply do. They absorbed most of the cracks and seams. We did lighten the load by about 200 lbs from one side to even the load and gain a bit of spring travel. It also brought the tounge weight down to an even 300lbs. So, after about 4,000 miles of cross country towing at altitures of 7,000"+, I can say that the TC will do most average tow jobs plus.A 2,000 lb gross should be very easy. A 3,000 lb load is possible. I do wish I has a gear between first and second. After having done this close to 4,000 lb load, I would not do it again. It is asking too much of the TC. Our Red Wagon will now make the trip tp Prince Of Wales , AK and lead a less stressfull life.
