As lanerd stated go get it weighed. Then adjust the air pressure in your tires. My 87 Allegro wandered all over until I weighed it and lowered the pressure. My current C was about 15 psi over on each tire and I lowered the pressure and it improved greatly. Last summer we went on a 13 state tour and the only wandering I encountered was driving in wind and that was only bad in Kansas. So start with the cheap before spending $$$$$ on fixed. You also have to remember it won't drive like a car or truck. You driving a house on wheels. And unless you have a large DP you will have a different feel.
