If this is for my post - I wanted surface temp reading. thx

No, they don't fly off in the wind, the magnets are VERY strong!

I was just reading a FB post from another Tiffin owner that discovered the ends of his supply and return air ducts are not blocked off. He made something to insert beyond the last opening and gained air flow. Something to consider!

There are a bunch of A/C postings going on this time of year. Most are complaining of not enough A/C to overcome the relentless heat in many areas of the country.
There may be a partial solution. I found, by accident, that the ducting in the ceiling is not plugged at either end. Neither the incoming air or the return air. The ducts are just open and the air exits into who knows where in the ceiling.
To check your duct work, remove the last incoming air register at each end of the coach and run a tape measurer into the duck work. Mine ran for about 36" in both the front and rear. Now, do the same with the return duct. Mine were again about 36" in each direction. They were just open with on plugs.

I measured the dimensions of the cool air and the return duct and fashioned a couple of plugs to close off the ducts just aft of the last duct in each direction. That is for both the cool air and the return.
After doing the plugging, it appears that the flow of air increased from all of the registers.
I am happy with the end results.

Another thing that we did was position our incoming vent registers so that the louvers are running in line with the coach. It may be my imagination, but it does seem to increase the air flow into the cabin.

We have the same problem, seems Tiffin doesn't put any insulation in the front cap over the windshield. I didn't want fiberglass insulation inside the coach, so I ordered denim insulation from Home Depot, installed in front cap behind cabinets and TV. Not only does this help with the heat but greatly reduces the road noise when travelling.

Did you remove all the front cabinetry to accomplish that? I saw that there wasn't any insulation in mine when I was working the passenger side cabinet with TV cabling but can't see any reasonable way to add insulation without removing everything.

Our coach is a 2003 the later units are different, but I used a cut off yard stick to get insulation into smaller places where I couldn't reach. Every little bit helps.

Early on in my 08 bus I insulated the front cap. I then used ac tape an foam to block the duct in front of the first vent and behind the last vent. Went one step further and used the foam and tape to isolate the front vents (all the front ac air forced out the forward 3 vents). Then isolated the mid and rear vents. This improved the air flow in each zone.

Significantly improved the comfort, as a matter of fact never was uncomfortable over nine years of traveling in Deep South. Not sure if newer models duct work is open front to back.

If only the dash air would have has worked as well as my current Entegra :icon_peace
