We just purchased a new 2013 Landmark San Antonio in March. After months and months of research, we chose Landmark. We had a Cameo Carriage, and finding a suitable newer model was almost impossible. The dealers and private sellers were keeping the prices too high. Since Lifestyle is a re-invented Carriage, they were priced higher than our budget for the options we wanted. We couldn't get a DRV down in price with the options within 15K of the Landmark. The same with the Redwood. We purchased our Landmark with all the options including the double pane windows, fulltimers package, yetti package, and more and 2/5 year warranty. If you put these options of any of the others, their price would be even higher. Yes, some options on the Landmark are standard on some of the others, but not many. So add it up and the better option IMO is the Landmark.
There is a fulltimer in the park with a New Horizon. It's a beautiful unit with 4 huge slides, Whirlpool fridge, Whirlpool separates W/D, and a 60" TV in the back. I think their are 3 or 4 tv's in this thing, but here is the kicker, he is towing it with a Volvo. Hmmmm! Don't think I want to go that way. Unit yes, truck no. Small Freightliner maybe.
We are fulltimers now for 15 months with plans for quite a few more years, and my main concern was build and customer service. If you go on the DRV owners forum, Redwood forum, and the Heartland forum, look and see who is most satisfied. We picked up our unit in Colorado Springs, and are now in Kenai, Alaska. Talk about rough roads on the Alcan near Destruction Bay, but the Landmark came through with minor problems. Called Heartland and ever item was Fedex'd within days. If you read the Heartland Owners forum, you'll see the DIY Mod section, and guys have come up with some very inventive mods to their rigs. You will see the Heartland company rep come on and comment, and they even in-cooperate some of those mods into their units. So take a look a deeper look than just frames and options, look closely at customer service. Good luck
