Hi, I have a 1999 Four winds fifth wheel 30RK SL- LS and the air conditioner needs to be replaced. The problem is, we can't read the serial number on it anymore and we're not sure what model it is. Anyone know for sure? We just need to know it will fit before we order it. Thanks!
pretty sure they are all the same size, shape wise. they do make models that have more BTU and also some that have heat pumps. If it didn't cool completely, chose one that has a higher rating.
