1: The absorption unit IS identical so you can do as you plan
2: I would not do it however
3: The reason... The A/C element is in the range of 300-400 watts.
So what does that mean: Well sometimes the DC element is de-rated (Say 200-250 watts in fact I think that's it) which means it won't cool as well. in hot weather it may not cool well enough. Also that's a 20 amp load, If it is in a trailer the charge wire from the Engine on the tow vehicle is not going to pass that much current. and on a Motor home you likely won't make it either. So it is a very short term solution at best.
There is a reason that 3-way units are hard to find now days.. and that is it. The 12 volt option just did not work well.
NOW what does work? Both dometic and Norcold had, at one time, a high effiency compressor job.. I have a small chest freezer that uses the same technology.
Instead of 300-400 watts. it sucks a great whopping 30-40 watts.. Yup 1/10 the power of the AC element. NOTE these are all electric fridges.
My freezer is 12 years old sometime this summer.
I occasionally defrost,, Blew dust out once. that's all folks.
