Hello. Our 2007 Chalet Arrowhead camper has a CCI propane detector, model 7770. There is no .2 after the model number in the operating instruction

Hey Mickie, thanks for the information! The CCI Pre Tell 21 model 7770 and 7770.2 are the same 12-volt LP gas leak detector. The updated .2 model had improved mounting brackets. The detectors were the same so the recommendations to replace your CCI Pre Tell 21 model 7770 are the RV Propane Gas Detector item # RS44FR in black or item # RS64FR in white.

The RV Propane Gas Detector item # RS44FR in black or item # RS64FR in white measure 4-1/4" long x 2-5/8" wide x 1/2" thick and are powered off of 12v just like your current one. They include two mounting brackets that measures 7-1/4" long x 3-3/8" wide and 5-3/4" long x 4-1/4" wide.

Is your CCI 7770 propane detector the original one that came on your Arrowhead camper?
