Does anyone have experience with this alternator from Patrolapart?

When travelling with the camper in tow I am charging a 900cca starter battery and a total of 450 ah of lifep04 in the Patrol and camper. I run 3 fridges, 2 50l Waecos in the Patrol and a 75l fridge freezer in the camper. I like lots of frozen food and cold beer!
