tlamb6463, all other issues aside (yes, I do believe that a few of the hundreds produced have many/major issues) I keep going back to your issue of things loosening up and/or falling off, ie; screws falling out, fenders & skirting loose, spare coming down & things falling through cabinet bottoms (including the possible flexing issue you describe).

This sounds like excessive vibration is the culprit. Short trips it's not noticable but, on long trips with prolonged (hours) driving, the constant vibration is shaking everything loose including the spare tire coming down and/or possibly breaking welds in the frame. Now, I'm not a structural engineer but, it seems like common sense to me that this kind of constant "pounding" would have to cause issues.

So, with that being said, have you had the dealer check the tires & bearings? Trailer tires are usually NOT balanced. The tires should be balanced and if it's as bad as it sounds, you may also have a bad tire that no amount of wheel weight will fix! Loose bearing (s) could be causing wheel "wobble" and vibration. Have them check the shocks while their under there. A bad shock can cause the unbalanced tire to just bounce uncontrollably exacerbating the vibration.

Just my 2 cents worth. Good luck!

I think every trailer mfr is going to have bad units it is sad that the pre delivery isnt better. Also bad on are part for not doing a better job of pre inspecting before we leave. My first year of owning are 2014 3600 we had alot of small issues. I had the putty coming out on my unit to I removed it and nothing else has come out.

Rracer5 I agree most issue seem to be vibration related. But in the beginning I could walk around and flex the sides of the coach easily because they didn't put any bracing behind any of the skirting. None. Just sheet metal hanging off the sides. As I drove down the road the sides flapped like a bird. This coach should have never left the manufacturer. For a company that has been in business so long these are rookie issues.

We had the skirt screw backing out, stripping out problem. I used drywall plastic wall ancors as nuts for the screws that hold the wheel well skirts on and the bracket screws.

Good solution on wheel well skirts. Are you having trouble with the screws holding the skirting on backing out? I need to walk around coach and tighten several of these up as well every time I stop to fuel up. Most are stripped out. This coach is only on it's second long trip. I just cant image what shape it will be in after a few years.

07 ThunderRoad has a good solution. But, now that I think back a little, I did have 1 or 2 screws loosen up . I took the screws out and squirted a dab of RTV on the screw and just put them back in snug. They never backed out again and can still be removed if needed or to do a more permanent repair.

Screws now hold tight with the plastic "nuts" on the back side of the skirt. I don't need to check and tighten screws at every stop. If a screw could possibly loosen, it can't fall out with the plastic dry wall anchor on the back. Yes, the anchors are a pain to install, but they are holding up well (and the screws can still be removed with no damage or cleanup ).
Note: I did NOT drill out the skirt and install the anchor into the skirt. I held the plastic drywall anchor, with pliers, on the back side of the skirt and ran the screw through the stripped out hole and into the anchor. For the brackets, I installed the screw through the bracket and into the anchor and tightened the anchor with the pliers.

I had to replace the "E" load rated tires with "F" load rated tires and had them balanced. I also found that the wet bolts on the spring mounts had NO grease in them ( including the 2 fittings inside the Equaflex center mount ). Bearings were NOT greased. My shocks are OK, but others have found bent damaged shocks not allowing the axle to move. Unless you picked up your unit at the factory, all R.V.'S are "used on the road". We have no idea what happened to it during delivery to the dealership. Tires; curbed, chuck hole damage, bent rim. Axle; bent, shock damage, bearings overheated. Front frame flex issues; improper hitch height, brakes and/or controller not adjusted correctly. etc, etc......

Here is our latest issue. Manufacture needs to take measurements to see if we have excessive flexing. Really? Picture doesn't speak for itself. Keep in mind they had just took the measurements the last time they had it.
