Hi All,I bought my 1999 Ram 3500 in 2001 and it came with the standard heated/power mirrors....Since I tow a 28' box trailer they where useless. I went to the dealer and purchased factory manual non-heated tow mirrors (power was not available) and have lived with those POS mirrors that will not hold adjustment (even after tighting up the mirror head) for 10 years...Now I find that I can replace the POS manual tow mirrors with power/heated.....Thanks for thread and I will contact A & M, order the mirrors, reinstall the joystick in the door and the heated switch is still mounted in the dash.....Looks like I am back to power mirrors, but in this case it will be power tow mirrors..I just joined this site and thanks again for the great info,Bob
