I purchased a Pecron E2000LFP portable power station to run my propane/AC refrigerator while traveling. Has anyone hooked up a portable power station to an RV through the prewired generator hook up? The Pecron has a 30 amp RV outlet but my RV wire cord is in the rear of my 2020 Pinnacle 32RLTS. Is there a better way to power the refrigerator while traveling other than plugging in the refrigerator direct to the power station? Thanks in advance!
