Lifestyle Frame

The box frame on the Lifestyle models was dropped mid 2016 model year. At the same time, the full wall slide models were dropped, too. It will be obvious as the late model I-beam frame models loose the side rear baggage doors.
Another thing unique to the former Carriage and 1st generation Lifestyle models is that the slide mechanisms sat atop the frame, therefore, no hole cut into the side of the frame to accommodate them.
The 2nd generation, or Titan II frame, has a hole cut in the side of the I-beam to accommodate the them just like the majority of all other makes.
I spoke the Quadra/Big Foot rep and was told that Lifestyle dropped them. I love my Bigfoot and have had no trouble or frame torque raising the front with one jack when I pulled a wire loose.
At any rate, Lippert has come out with a new system similar to the Big Foot where as each jack is self contained like the Big Foot product.

"I was under the impression that even though the DRV frame is built by Lippert the frame is still a triple stacked box frame. Not an 'I' beam. Far superior than an 'I' beam."

Yes the lower frame is two 2x6 tubes and one 2x3 tube stacked and welded together to form a 2" x 15" frame. The "I" beam is fine but there is a point that it is not.

Any real evidence that Lippert is still having issues with their frames and have not "fixed" the problems of old?

There is NOTHING wrong with a Lippert frame as long as the RV Mfg has not specified too light of a frame for the application.

My "LIPPERT" frame on the MobileSuites production line.

I was under the impression that even though the DRV frame is built by Lippert the frame is still a triple stacked box frame. Not an 'I' beam. Far superior than an 'I' beam.

There is a nothing wrong with a PROPERLY designed I beam or C channel frame if it is designed properly. The stacked rectangular frame is stiffer and lighter weight than an I beam frame....basic engineering principles apply here.

I have seen 5 Montanas with the common broken frame....all were torn metal NOT the welds. Just looking at the design if you know anything about welding and metal structure you can see its poor design and material choice.

Not disputing you, as that's an issue, too, but several of the ones posted here have =started= with a failed weld, that led to metal failure. There weren't weld failures when a bunch of the i-beam frames failed in the suspension area a few years ago. I'd be willing to bet that <100 lbs more steel in most frames would make them near-failure proof...PROVIDED, they're constructed well. I'd sure-as-hell sacrifice 100 lbs of CCC for a worry-free frame.

It was my understanding they went to an I-beam when they went to wide body construction, 102". If you look at their website, the models that say dealer stock are the old, box frame, and the others are the new I-beam, wide body frame.

In my experience the fact that Lifestyle uses the 4 point system is because that is what Bigfoot sells. I suspect that BF made them a good deal on price. The stacked frame on the Lifestyle ends just behind the wheels, which is where the jack is. The rest of the way back is single box frame that will bend if jacked in the rear.

Not even the 6 pt has jacks in the rear. The furthest rear jacks are right behind the wheels.

Well to further support the rumor that the Titan box frame went away for 2016, the website shows the three full slide models as discontinued. They always bragged that they could do a full slide because of the Titan frame.

The key to a good frame is the engineer designing it no matter what material is used. Lippert has predesigned frames that some manufacturers design a rig to fit and others design their rigs from the ground up. I will bet that the majority of Lippert frame issues involve the design to fit frames.

Equal to good design is a good build. Welds with no penetration being probably the #1 culprit in the majority of frame issues, IMO. Blame goes to both the frame manufacturer, no matter who, AND the RV manufacturer that doesn't QC the frames as they come in and either fix problems on the bare frames =before= building the RV or outright rejecting the frame. I will admit that frame issues seem to have been far fewer in the past 3-4 years, but there are still a lot of older RVs out there that the manufacturers should step up and fix, no questions asked, if/when the frame fails.
