We don't have the remote start version, but our 3400 works great on propane to run AC and microwave at the same time in our 825 with no issues. It is only slightly louder than the Honda 2000 (59 dBa vs 57 dBa), but it is bigger than the Honda 2000 and it does weigh just under 100 lbs, so storing it for travel is more challenging.
The 3400 has wheels, so I built a 6 foot plywood ramp to pull the generator into the TC and it stores nicely under the dinette table. The ramp lays flat on the TC floor when travelling, which also prevents side-to-side movement of the 3400. Then, we pull the ramp out at the final destination, roll the 3400 down the ramp and padlock it to an immovable object for security.
