Without the full number I don't know exactly what your BTU rating is so you could need the # ACCOL135 (13,500 BTU) or # ACCOL150 (15,000 BTU) if you're just wanting to replace the rooftop unit and keep the rest of your Coleman system in place. You can always go with a higher BTU rating than what your system is but you wouldn't want to go lower.
If you're wanting to replace the entire system then for 13,500 BTU's you would need part # ACM135C or the # ADV94FR if you want a wall thermostat. For 15,000 BTU's you would need the # ACM150C or the # ADV64FR for a wall thermostat.
If you look at your rooftop unit with the shroud off there should be a sticker somewhere that lists the BTU rating so that you can choose the correct system.
