Again, I believe those tongue weights don't include mandatory accessories like batteries and propane tanks, and the added weight of those will be almost entirely added to the tongue weight. So right there, without any gear whatsoever, you're overweight on the tongue alone. Real tongue weights, as measured by folks here, are much higher than 350 lbs.......

California law requires brakes on trailers with a GROSS WEIGHT over 3,000 lbs, so that means all the TMs except the 2400 series are automatically excluded. Can you carry less than 700 lbs in a 2417, including a battery, propane tank, propane, clothes, food, etc. Maybe, but doubtful. LoveToCamp's 2417 was nearly 3,500 lbs. But even if you could, would it be safe? Would you feel silly if you got in an accident with your trailer that has brakes you weren't using?

I have no doubt you will be able to find someone, somewhere, towing a 3,500 lb trailer with a Flex, even with trailer brakes. It doesn't mean it's a good idea, ESPECIALLY when towing in the mountains.
