Beef up (fish plate) “I” beam frame

All I can say is you better have the underbelly and insulation removed. Also have a couple 5lb ABC fire extinguishers handy.

I will use 3/16 plate 12 feet long min. I’ll jack the back end up a hair if need be to true it up.
Thanks for your comments.

Are you sure what you call rear frame sag is not frame camber by design? Perhaps a call to Cedar Creek or Lippert is in order? If you start jacking out camber designed in and holding it by welding in flitch plates or stiffeners, you may create issues you currently do not have.

Now my Mobile Suites Lippert frame is hell for stout because it was designed to meet DRV's specs.

I know of two people who own DRVs, one a camp host who I know like a brother, and both have been back to the DRV factory more than once for frame issues up at the front.

Never said they are perfect but they have very few issues. Mine is rated 21k, it's 23k with a 5,800# pin with zero issues.

The manufacturers know exactly what LCI is engineering and chooses to accept it. They accept it because all the liability is on LCI, and they're cheap, which goes straight to the bottom line. When something fails its on LCI's nickel, not the manufacturer, even if the manufacturer gets involved which they don't have to, and most could care less.

That doesn't say much for the manufacturers if they do "under spec" the frames and other components to save money,although it is much the same with auto manufacturers. Even if you think "you get with you pay for", that really doesn't mean anything anymore. Manufacturers will still use the cheapest **** they can get away with like putting lipstick on a pig, it's still a pig even though it is pretty.

At the same time, LCI =could= have said to a mfr that they would refuse to accept a spec, given the end product, but no, they simply built it, did a cr@ppy job, then refused to warrant their junk.

Lippert makes what the manufacturers want. If the manufacturers wanted stronger more durable components, they would get them; as long as their willing to pay for them. Suppliers don't make a bunch of frames then go see if someone wants to buy them. Suppliers build frames to the manufacturer's specs. The price and specs are negotiated before the supplier even turns on the light switch in the plant. Everyone is on the same page and knows exactly what is what. The manufacturer is getting exactly what he wanted and paid for.

I don't disagree with you 100%, but I will say that LCI's =build= quality, no matter the spec, leaves a lot to be desired, though it does seem to have improved the past several years. About 8-10 years ago, there were =lots= of post here, with pictures, of broken frames and, especially, broken welds. Many of those welds, while pretty, had little to no penetration, so were mere decoration, with little to no strength. This led to other problems, including broken frames, mostly in the pin box area, around the suspension and in the frame step area. Sadly, the mfrs refused to really inspect the frames and either fix them before building on them, or flat-out returning them to LCI as sub-standard. Had the mfrs, as an industry, been willing to go draconian on LCI back then, you'd've seen a lot fewer frame issues, IMO.

The manufacturer may spec what the frame needs to accomodate, but LCI does the engineering. The manufacturer has 0 liabilty should the frame fail, unless they choose to assume some of it. LCI warrants the frame. LCI sucks and essentially has a monopoly. They bought out almost every other frame fabricator involved with the RV industry or undercut them out of business systematically. The RV industry sucks as well. Birds of a feather.

This! As well as a few other established, reputable RV component manufactures....then outsourced and/or lowered the quality! memtb
