Fifth wheel towing with an older truck

Although I am new to this forum I am not new to RVing. I have a Elkridge 34tsre that my wife and I stay in for three months to get away from the snow up North. I am considering the purchase of a much smaller fifth wheel to take trips for the other nine months. I am the original owner of a 2002 Chevrolet 2500HD with the Allison transmission and 8.1(gas) engine that has around 120,000 miles. This truck is in great condition and seems to be mechanically sound. My question to all of you is - would you think that using this older truck to tow cross country would be smart idea or should I try to find a used truck with less mileage? Thanks in advance.
