Hey Darren! Do you know the exact model of your Parallax 7300? There are different ratings and styles within the 7300 series. WFCO with the auto detect is a good option, but you're going to need to match it up with what you have now. You can choose from the following based on your Parallax model or output:
-Parallax 7335 (35 Amp) - WFCO RV Power Center - 35 Amp - Auto-Detect # WF28FR
-Parallax 7355 (55 Amp) - WFCO RV Power Center - 55 Amp - Auto-Detect # WF86FR
-Parallax 7340 (Deck Mounted) - WFCO Auto-Detect RV Converter Charger - 35 Amp # WF26FR
If you have a different output or a model not listed above let me know in the comments below and I'll see what else is available. What kind of camper do you have?
