Muffer Support - is this by design/or need to be fixed?

[tullywork]

Long story short...my buddy (who's owned an RV for 10+ years - although doesn't claim to be an expert) was camping with us (him and his family in his RV and our family in our RV) and happened to look at my motor muffler and said "looks like it's hanging, your going to need to get a bracket and fix that'...I've done that fix a couple of times...it's easy just go to AutoZone and get a 'kit'"

I've got a 2015 Thor Windsport 34J

Seemed 'OK' for the short term (wasn't close to hitting the ground - seemed secure when I tried to wiggle it), so we kept on camping/traveling...got home and went to AutoZone and bought the support and bracket to mount it to the frame...went under the truck (I'm a buy all the possible tools/parts and return what I don't need type of person) and I couldn't figure out where to mount the bracket...then looking further down the muffler pipe, I could see about 3' (toward the center of the truck) it seemed to have pretty secure mount point.

(picture attached)

So here's my question: in the attached picture you can see at (1) the muffler is attached to a support that's secure to the frame (no issues)....but that seems to be the ONLY support for the muffler (which is maybe fine?)...but at (2) I see another 'bracket' which is where I expected to have to secure it to another part of the vehicle frame, but above it is the sewer connection compartment (grey/black water tank outlets), so it wasn't completely obvious how I would secure a mount. After inspecting it further, I wondered if that bracket was just to secure the two pipes together (it's not one long pipe a ~3" pipe connects to a larger ~4" output) I'm sure I could figure out something, but after looking at it, I wondered if maybe it was unnecessary?

Hoping someone with a similar RV could help clarify if there is an issue that I need to address or if this is 'by design' and everything is OK?

Thanks in advance!

Here's a pic of mine. And it's not the muffler, it's just part of the exhaust pipe, with the clamped on tip.

Thanks - sorry, I'm not much of a automobile-guy, I've done more with this vehicle (from a DIY maintenance perspective) than any of the 10 or so vehicles I've owned in my lifetime, mostly because there don't seem to be any 'RV repair' places anywhere near me in Northern NJ. Although I'm looking forward to a visit to a 'truck repair' place this afternoon to hopefully get some much needed assistance!

So based on your picture, it appears the same - clamped on tip & exhaust pipe support near the center of the vehicle underside - so looks by design...?

The V-10 moves around a lot due to the softness of the motor mounts. Evidently Detroit Chassis thinks the one large muffler hanger aft of the muffler is sufficient. The only problem I have is the whole assembly has a resonance at 50 mph in 6th (1,650 rpm) causing the tail pipe to hit the heat shield. As I am seldom at 50 mph, it is no a problem and if I am gong to travel at that speed, I just engage tow/ haul which drops the coach into 5th gear.

The V-10 is a "Weeble": it wobbles; but it never falls down.
Beau is right... they left room in the system; for things to flex a bit.

Got it! Thanks for the info and clarifying! Appreciate it!

Muffler bearing fuse housing regulating the pneumatic fluid.
It dims the light in the gas nozzle neck at night so it doesn't blind you.

The clamp in the foreground is just to hold the exhaust extension needed so the stock exhaust pipe will exit outside of the nonstock wider body. I would work as an extra strap hanger if you decide it needs one.
