A Tahoe, even a PPV, is essentially a short-bed Silverado. Certainly it can tow, the differences are in what makes a PPV different from a standard Tahoe, like electrical, gearing, braking, stuff like that. If your trailer is light you should have no trouble towing it. I would search out auto wrecking yards. Most accidents are at the front of the vehicle so the rear end where any hitch stuff is located should be undamaged and easy pickings.
