We have a new 2024 2605RBWE Keystone Passport and owned it for a little over a month. It has had a lot of towing issues with heavy trailer sway noticed in a 1 ton Ram. Currently also having its second shower leak repair. Dealer has stated there is not any issues with the trailer towing. However, I am not too sure if the underbelly covering is supposed to be this close to the axle. when we purchased the dealer said this was just the tanks hanging down and the covering sagging this far down is normal… I am starting to question this.

This does not look normal to me. I would probably remove the covering carefully and peak under that, to see whats up.

I don't feel like this resting on the axle is the cause of the sway, but maybe? FWIW this is very similar to my trailer, and I don't have sway issues, and pull with a 1/2 ton truck.
 
So the dealer says that caroplast sagging is normal? There are a lot of words to describe that but normal is not one of them. If the tanks are hanging down they need to unhang them. Good grief.
 
Coroplast is secured along the frame rails, with an occasional screw in the center where there is a crossmember. The coroplast on my Passport would sag a little because it flops around as you move down the highway, and I had to add some fender washers to help hold it up. HOWEVER, what I see on yours is NOT normal in any way. You can see where the coroplast has actually stretched and flattened out the corrugations due to some strong force. I would suggest pulling a few of the pins holding the coroplast in place and getting a good look up inside to see what really may be going on. The tanks are supposed to be above the frame rails and have straps that prevent them from dropping in the event that a mount fails. Another user here had a tank drop and it was determined that the factory failed to install the straps, so anything is possible. You need to get a look inside the belly.

As for handling, although you obviously shouldn't need it, are you using a weight distribution hitch with sway control? Our truck could easily handle the Passport without one, but the trailer handled terribly. As long as we used a weight distribution hitch with integrated sway control, it handled fine. It got even better when we replaced the "squishy" sidewall Trailer King tires with more robust Goodyear Endurance tires.
 
When I look at the photos it looks to me like the Coloplast is transmitting the shape of a tank. That is not ok. Don't accept the dealers excuse. It should never have been ignored if a PDI (pre delivery inspection).
 
Another quick check could be to just press up in the area of the sagging coroplast. If there is any resistance its probably due to a improperly strapped tank. But if the tank(s) are sagging that badly, I would expect a leak somewhere at the very least out of the coroplast?

When it gets fixed, if they don't replace whatever tank is sagging there, or whatever is causing it, I would request to see it up close prior to them reinstalling the coroplast, or some good clear pictures or something. It would be a waste of everyones time if they strapped up a cracked tank, that shortly fails thereafter.

You mention a couple of times that the "dealer said"... First about the towing issues, then when picking up the trailer, the tank/coroplast issues. WHO at the dealership told you those things? Was it a different person in a different capacity at the dealership? I'd guess that the "sales/PDI team" was the source of the tank/coroplast statement and a "service writer/checkout person" was the source of the towing issues.

If that's the case, have you elevated both problems to the service manager and/or the general manager level??? You should not have any issues towing with that truck/trailer "IF IT IS SET UP CORRECTLY" and that "tank/coroplast issue" is definitely not normal...

If you get no satisfaction by elevating the problem, then it's time to seek a new service center. If there are none available that will accept your warrant work, then I'd send those photos to Keystone, get them involved and ask them to "guide the inspection/repairs" or locate a new service facility that can correctly inspect and repair your trailer...

This is an opinion, not fact (at this point) but I'd suspect that after they got your money, your dealership is not interested in keeping you and your trailer as a long term customer.
 
"Shower leak repair" Sounds like there might be water in the bottom or they pulled it down to find the leak.
Towing issue might be on you. You should check all air pressures in trailer and truck and be sure hitch is set up properly to correct height and if using a WDH that it is set correctly. I would not depend on the dealer and their help, it's you in the truck going down the road.
 
If the tank has fallen off its mounts it could be moving around a lot while towing. Probably would cause visible damage inside though but just a thought.

You need to get it back in to the dealer and have a conversation with the service manager.
 
Your pictures indicate a problem that your selling dealer needs to be front and center on. It's not loose coroplast nor anything else that is "normal". Whether a tank that has fallen, inside leaks that are bulging the coroplast (don't think so) or ?? the dealer should be 1) jumping on this "right now" because something is really wrong and 2) giving you proper guidance and info regarding it vs what sounds like pure "silliness". You need to be at the GM or owner level and make them dig into it vs just placating you and sending you down the road....until the warranty expires...and they can charge you their labor rates for repairs - don't do it.
 
Thank you all for the input. We have been working directly with a warranty manager at the manufacturer. They are going to have the service center look into the coroplast issue.

For the towing portion the dealer/service center provided frame measurements to manufacturer and said it was all in spec. Dealer provided a 4pt curt wd hitch to upgrade from the 2pt curt wd hitch. Unfortunately still had the towing issues. As a goodwill effort the manufacturer is providing us with a Hensley hitch so hopefully that will work?

I think it might be time to find a different service center. Unfortunately, we have escalated as far as we can.
 
Call keystone support directly and inform them of the hack job your dealer is selling and see if they will authorize another dealer to look at it.

At the least have someone from another service center put eyes on it.

Odd, because I run the 4 pt Curt hitch as well. I think its called a Tru-Track? Anyways, you might want to read up on how to set it up yourself and invest in the tools to do so. I don't have much faith in dealers to set up correctly. Don't get me wrong, I've had a couple do a really good job at it, but most others just wing it, or set it up based on perceptions of how you might load truck/trailer, and are often off the mark. Its not that hard to do, once you know how, but it can be time consuming to get it just right.

As for that style of hitch, if its like mine, it has these ball bearings that sit in a "detent". My understanding of it, is when sway starts to occur, and that bearing is out of the detent, the hitch is trying to force it back to the detent. This action could "feel" like sway, but may actually be the opposite. If your not used to how that works and feels though, you could be misperceiving it. Just depends on how severe it is. It does feel much better when it is right though. Quite a few factors at play, like the rating of the bars they gave you with the hitch, etc.

When my dealer set it up, I didn't care for it much at all...and that opinion was voiced loudly by my wife. It was always "great" on good days with no wind, etc. but maybe only "good enough" on windier days, more passing traffic. Eventually I had enough, bought the tools, found the flattest area I kind find to set it up and spent a couple hours in the instructions and videos, setting it up and measuring, then readjusting and measuring until I was satisfied. Has always been "great" ever since.

But what took me 2-3 hours took my dealer maybe 15 minutes? And I don't recall any measuring of any sort going on.
