Looking at the data for a 2004 Coleman Tacoma, the OEM tires were probably B78-13ST. This roughly translates to 175/80/13 tires.  With a GCVW of 3,000 pounds you should look for a Load Range "D" tire. This means you will need to find a bias ply. I found my latest set at my local Discount Tire shop. Pep Boys also has them available for higher cost (and 20 more miles away).  Les Schwab could also get them but they only had one in stock at the time.
I got about 10,000 miles over 6 years on my last set of tires. I attribute the life to having a single axle, maximum inflation, storing indoors, and not exceeding 70MPH on cool days and 65MPH on hot days.
