pt4 F350 w/ Lance 11'6 | 1st camp with Bluetti AC70 and still ran out of power, what did I do wrong?

Yep, Bluetti works like your plugged into shore power. It will run the entire RV/Trailer/Camper as if it is plugged in and charge your "house" batteries. Besides keeping it for my home power outages (2000 Max), I like to bring it camping after about 3 years of RV house battery use. Meaning my batteries start to draw down quicker than when I first purchased. The load kills the batteries pretty quick (after 3 years I lose about 30% then drops from there.) so I then take the Bluetti with me as a safety backup power station. Especially when government campsites say no generators until 10am. We use it to keep us going and charging up the RV until 10am. (New batteries on coach(1 - 2.5 years old) I make it to 10am easy without the Bluetti help, but after 3 years, the batteries make it to about 7am.) It helps us make it to 10am so we then can fire up the generator to top off the house batteries and recharge the Bluetti until the next day. It will charge up your existing Camper/RV/Trailer batteries. But the key is to have good batteries and change them out every (For Example) 3-4 years (If you're lucky). Suggestion you should purchase 2 x 6v golf cart batteries. Much better than 12v. You will get like 215-225amp hours per battery vs a lot less (Varies per battery brand) with 12v, But with the 6V deep cycle, you need to add water regularly (Every couple of months) or you will kill them.

My favorite part was when your wife brought you a beer!! Lol

U guys still in Italy? Just graduated Tarquin yesterday and the wife is wanting to start camping again.
