We own a 2025 Delta 292RL and absolutely love it. We've had a few very minor issues with it, all of which I handled with Alliance myself. In my opinion, the Delta 292RL has a lot of advantages over our previous 2022 Grand Design Imagine 2670MK. Alliance uses Azdel composite panels instead of the Luan backed panels that are prone to rot when wet. Alliance also only uses rack and pinion slide out systems on the Delta 292RL. Our old Imagine 2670MK used the problem prone Schwinteck slide out mechanism on the kitchen slide out and it was a constant source of worry for us. The kitchen slide out on our old Imagine trailer would sometimes get stuck going in or out. Fortunately we were always able to get the slide out to work properly, but I felt that it was just a matter of time before we had a real problem with it. Friends of ours were on 6 week trip and their Schwintech slide out failed 2 weeks into the trip and they unable to use it on the rest of the trip. This may not sound like much but I can also operate the slide-outs and awnings on our Delta 292RL from outside the trailer as well as inside. With our other trailers, opening the slide out and awnings was often a two person job. One of us stood out side to watch making sure that we didn't hit something. Alliance also made the pump and solar control very accessible and easy to find. It's behind the panel in the pass through storage compartment. In our other trailers the pump was never easy to access, it was either buried under cabinet or hidden under a random drawer.
We tow it with a Ford F250 Diesel using a Hensley Arrow hitch.
Lastly, whatever trailer you buy you should follow Chasewston's advice and make sure that you test everything. If you have any questions or comments feel free to reach out.
Best of Luck.
