Repair or replace?

Good points everyone thanks! Would it be wise to go back with same brand which is a off brand of Coleman I think.if not what brand is best?

It's almost 10 years old, go for new.

Most a/c units are pretty puny as far as material. Replacing the compressor may only buy you some time before another failure. Then there is the ability to evacuate the charge then recharge the system as most of these RV a/c systems are usually sealed and not field rechargeable. Being a 2007, that a/c may have R22 which is becoming scarce(expensive too) as R410a began replacing it in ~2009/2010

I would probably be just as cheap to replace the unit, by the time you remove the unit from the roof, buy a new compressor uninstall the old one and install the new one, pump the unit down a couple of times, buy new oil and refrigerant (which is not cheap) you could remove the old one and set it aside for spare parts, install the new one and be on your way. (my opinion)
