I have a Talon 313 and love it. Yes, the generator can be heard while running but itโs not that bad and it does not vibrate the trailer.
When we dry camp, we typically read in bed at the end of the night so we are over the generator when itโs running. Jayco did a good job insulating the bedroom so the noise from the generator is minimized.
The 313 is a great unit and so far we have have had minimal issues with it. If you do get one, make sure to have your dealer check all the propane and fuel station connections. The ones on our unit were only finger tight.
Also, check the wiring for the motors on the slide. The wiring for the rear motors goes through the wheel well and ours was only duct taped to the bottom of the trailer. The tape added coming loose and the motor connection ended up rubbing on the top of the tire while in motion. Luckily, I found it before the tire wore through the wiring and the connection. Ended up wrapping the motor connection with electrical tape and zip tied and screwed the slack wire to the top of the wheel well.
Good luck with your search.
