insulation repair
Joel Ashley:
Roger Berke, administrator at the AquatHot forum on Yahoo!, replied to my inquiry on your behalf. He only said the insulation wasn't an AquaHot/Vehicle Systems part, and that it was likely Monaco installed. I suppose it is even possible that some owners installed their own and/or it was offered at some point by a vendor. Roger did not answer my question about a possible source for replacement insulation. :-/
Some possiblilities I found are at http://www.autobarn.net/copper-exhaust-wrap.html, and http://www.boostplanet.com/exhaust_wrap.htm, among many others. Everyone seems to be offering the same Thermotec material.
Other than replacement, I'd suggest one of two options: use special "aluminized" heat resistant duct tape to wrap the frayed insulation; or simply remove and discard the stuff. If your coach is only a few years old and the material is that frayed, by replacing it you'll only get the same result in a couple years.

Thanks Joel and Gerald for your help, with the links and infomation you have been able to get, I should now be able to do a repair/removal of the old product.
I will let it go for a while then most likely just remove it from the pipe.

Marty and Suzie Schenck:
Perhaps a previous owner added that because they boondocked where there was long grass. That would help prevent causing a grass fire. Here in Washington when catalidic converters first came out they had to insulate them on some emergency vehicles because there were a couple of instances where they caused a grass fire.

Hi Marty,
That's pretty much what I guessed but I think this product came off the Assembly line, it's not a bad idea but as Joel and Gerald have found out no one else is adding this Product, I think I may try to just add a wrap of the copper product, this actually may hold up better. I really don't know if it's worth the 75-100 bucks!
I will do some checking around just to see if I can find something or just pull it off I do very little dry camping.

Jerry-
Here is an another possible source, though I didn't readily find a precise replacement product: http://heatshieldproducts.com/.
Most exhaust insulation products are in the form of wraps, but what we're looking at is in sleeve form. If you do find it, it will likely be ridicuously expensive to buy the length required.
I suggested earlier the duct tape wrap, and still think it a viable option. Available at hardware stores where furnace and other ducting is, the product I have is aluminized, made by 3M, and is more heat resistant than regular old duct tape. You could use it first horizontally along the torn sections, then band every 6 inches or whatever around the pipe to reinforce, gather in, and secure the frayed areas.
The high heat duct tape would be an inexpensive quick fix that would allow you to keep the original probable purpose of the insulation, fire prevention; and, when worn down by road hazard over time, it could be readily replaced. The repair might not look as clean and snazzy as a whole new sleeve, but who but you and your mechanic look under your coach anyway? Okay, maybe Bill Sprague ;). Any other reason you might have been on the ground at the Sound of Music Rally, Bill?
