Am looking at a 99 Chevy CK3500 6.5 Turbo Diesel 4 door, single rear wheels. I've heard conflicting reports on whether this truck will handle an 8 ft Fisher mm. Can someone give me the straight dope. Right now we plow with a 85 CK3500 Diesel dump and a 97 Chevy Ck 2500 Ext.cab gas with no problems. Some guys have told me the diesel is too heavy along with the 4 doors... ?
