Normally if you ask me about LG electroincs I say LG stands for "Lousy Goods" and the DOMETIC microwave in my 15 year old RV which was and is really an LG model is no exception. brand new it DID NOT WORK properly and in fact could not by design.
Thankfully... The problems were in the area I studied in college so I was about to swap an LG part for a GE part, make one other minor change and it works fine.
I can not tell you what is the best.. I'm kind of partial to Panasonic products when it comes to Electronics but... I really can't tell you how well they will stand up in RV service.
Home was where I park it. but alas the.
