I am using a buddy of mine's 3 car trailer that he uses in his used car business. Do NOT want to use his 5th wheel cab truck but am looking to RENT one to drive to Michigan and pick up two new GMC units that I bought. A Denali and a Sierra. Anyone know if there is a nation wide "specialty" truck rental outfit. (already tried Penske, Hertz, etc..) I live In Illinois. THANKS.
