We bought our 2014 3402rl about 3.5 years ago and paid about twice that. It was used but like new in condition. It had slide covers, 6 point hydraulic level up system, and two ACs. Extended warranty replaced front AC in year two. No other major problems except the China bomb tires and junk oem recliners. Upgraded to disc brakes, g-rated Sailuns, king bed, and a Dometic 320 in bathroom. Had to change the faucet in the bathroom to make the sink usable. I'm nitpicking now. Our trailer has been great for our needs and if the one you are looking at is in good shape, buy it and enjoy. You will need at least a 350 or 3500 SWR to handle the load. Good luck and I would be glad to answer any specific questions about the 3402rl.
