Ive been eyeing the same setup and had some questions/thoughts.
Will the 200 series alternator care much about the extra 800watt power draw needed to quick charge the Ecoflow?
The DC-DC charger is said to get very hot during use. Might get annoying during summer trips.
Fellow Houstonian here too. Just picked up a white 2011 LX with 96k miles and have been looking for a reputable third party Lexus shop. This is a great discussion. My vehicle seems to drive well but I do think about if its time to change all the fluids.
Have you found a shop that will do...
