The frames are outsourced like many other items and Escape merely attach their fiberglass moulds onto them.

Although it may still be popular in more rust-prone areas, not many people here (which is definitely north as population distribution goes) use aftermarket rust treatments... although some new car dealers make some extra money suckering buyers into undercoating to go with the "paint protection". Most of the aftermarket products are oily coatings that require regular reapplication - not something most people would want on their trailer frame. Even the permanent coating is sticky and unpleasant to deal with (we had it on a Honda which we purchased used).

Yes, but - unlike most components - the frames are custom-built to Escape's specifications. They're not an off-the-shelf or catalog item. Of course the supplier is an experienced frame builder, so their expertise is contributed to the design and specification - I'm sure they don't just blindly build whatever is asked. If the finish needs to be changed (and it seems like that is an opportunity for improvement) then Escape Trailer Industries can specify that change and have the frame shop do it.

This is somewhat like Toyota's experience with the Tacoma frames (which were the subject of a recall due to excessive rust). It is a Toyota component, designed by Toyota, but constructed and supplied in complete finished form under contract by Dana.

Have used it too . Pretty good . Pat

While traveling in Europe last year I noticed many travel trailers with galvanized steel frames. Boat trailers are built this way here. I expect there would be less welding and more bolts to build the frames with galvanized steel. It would be a nice upgrade to stop the rust problem.

good info..being from the south and not really having to deal much with snow/heavily de-iced roads...always thought that stuff they sprayed on the underside of vehicles for folks up north was something like that tough coating they spray coat as a bed liner in pickup beds...which in this camper's truck bed seems very durable, certainly more than paint...also used to use what was described as a 2 part Polane paint on steel in manufacturing..of course the paint process was rigorous and the steel had to be properly de-greased after fab/welding....paint job so tough it was difficult (but not impossible) to scratch even with a chisel.

My recollection of that undercoat was that it was like a thin layer of asphalt. Rocks would chip it and the water and road salt collected under it. Case of the cure being worse than the disease.

Had an inkling in the back of my mind that galvanized steel doesn't take well to paint. Could be a lot of trouble for little gain. Link to "The pain in painting galvanized steel".

In the Parks we went away from steel picnic table frames and went to galvanized. We spec'd hot dip galvanized after all welding was done. Worked very well. When we had to paint galvanized, we used to use a product called galvagrip. Worked pretty well. By the time I retired most of our 1200 tables were galvanized frames, many with dipped tops coated with Plastisol, a rubbery thin plastic that was very durable. Park benches the same. Galvanized is very nasty to weld. Bad gasses

The bedliner-type material would be somewhat similar to one of the layers of coating used in some areas of the body by vehicle manufacturers, and tougher paint than used on the visible panels is used as well. I think after the vehicle is finished is too late to get something like this to stick properly (due to those surface preparation issues), and in any event that's not what the aftermarket providers do.

Yes, that's the sticky stuff I mentioned. I dislike it for those reasons, and more.

While galvanizing is sometimes used for frames welded together like an Escape frame, it's an expensive way to go. U-Haul uses a lot of galvanized frames; apparently it is worthwhile for durability in these heavily used rental units. Those European frames are typically bolted together from modular components of stamped sheet steel, and are built by major suppliers (such as AL-KO), who typically supply the complete chassis - frame, axles/suspension, and coupler.

There is one North American supplier of frames like this (bolted together from stamped components), but they are e-coated and powder-coated, not galvanized. It's the Ultra Frame from BAL (the same company which supplies stabilizing jacks to Escape).

Galvanized: can't reasonably weld it, can't readily paint it, can't even drill a hole to bolt on a bracket without causing rust to start at that point. It's a great way to avoid corrosion, as long as you never intend to modify the frame, and don't mind the appearance of the raw galvanized surface.
