F450 and risers

Littlebaler,

If its only 1" that may work out just fine. Some of the measurements I have seen on the F450 bed rail height have me a little concerned. But ----- we deal with it when it gets here.

thanks

Don

Not yet, the only "filters" that I have found are the foam inserts in the ceiling vents for the AC units.

There is no filter nor any duct work for return air for the furnace.

Yep, we got some matching Honey Cherry trim from DRV and enlarged those to utilize 12" x 12" residential HVAC air filters. It REALLY helped the airflow from the A/Cs! I was going to change out the furnace filter just to get ready for fall/winter, but darned if I can find it. On our 2004 36RE3, there was a grille under the steps that snapped open to get to the filter. I can't find anything that looks like a return air grille for the furnace on this 38RSSA.

Rusty, no return filter for the furnace on our 39TKSB3 or last 36SB3.

I am curious about what you did for the AC return air. You have any pics ???

Ron,

This is on our daughter and son-in-law's Mobile Suites. Ours is the same except the grilles are cream-color to better match the ceiling, and of course the trim color is different. But you get the idea.

Rusty,

I'm not seeing any pictures. I am very interested in what you did.

Our unit has a small metal vent behind the toilet that dumps into the basement area. No filter on it. We then have another grate/vent above the pantry as you come in the entry door that is about 1'X2'. That does have filter material behind it and that has a small open area up high that looks like it dumps down the wall between it and the bathroom. I guess the heater could pull air from either or both these areas.

Have you removed the wood framed 1' X 2' screen to actually see a filter???

Yes I removed it yesterday. On the back side of the screen it has a black foam that looks like filter material. It could just be there for looks, I have no clue.

Everyone take note I WAS WRONG!!!!!

I DO HAVE a filter stapled on the back side of my 1' x 2' screen above my pantry. There is a hole behind it above the pocket door track that allows the air to travel down thew wall behind the toilet. The grill behind the toilet does NOT have a filter.

My big screens filter had hardly any accumulated dust, that did not seem right for one year's use. When I found out the big screen has little dust it all made sense because the return air will go thru the point of least resistance.

Bottom line my furnace has had LITTLE filtering and MOST of the return air comes from the toilet!

I will be installing a filter behind grill.

Yes sir that is what ours looks like. When I took the vent off behind our toilet and found no filter I decided I would be installing one before we start getting cold weather. I need to pick up more filter material from Lowes or HD and cut to fit.

I think I am going to use a less restrictive filter media on the toilet and pantry return. I am also going to make the return air openings larger and use less restrictive filter on those also.

I added some extra LED lights yesterday. I needed to remove a few AC supply grills. I would advise checking the condition of the foil tape. I found it VERY lacking with one area that was a couple inches around allowing air to blow into the attic. This was in the bedroom area. I will now remove all the supply vents in the living area next. Smooth silver foil tape is what to use. Very easy to work with just pull apart with fingers.

I have pulled all our supply vents and only found one in the living area that was not sealed good. A couple of pieces of foil tape and it was good to go. I also went up on the roof and pulled the AC covers. I then pulled the cover off the supply side and found some areas in there were we were losing cold air into the attic. I was able to seal those up which has helped. I believe every little bit helps on these things.

Another area to check is the heater itself. Ours has easy access right behind the rear pass thru storage wall so I had my wife turn it on and I could feel a couple of places warm air was escaping on the unit and was able to seal those with foil tape.

Joe,

Again, this is one of the return air grilles on our daughter and son-in-law's Mobile Suites. Ours is similar in design but with cream-colored grilles and honey cherry trim from DRV.

One more thing you might want to check if you have an kitchen island. When we got our trailer I went around outside and sealed every crack or hole I could find which was not many. We then turned our attention to the inside and did the same. One of the largest openings inside was under the kitchen sink where the drain pipes and water lines came through the cabinet floor. I sealed that area with expanding foam. We had noticed when we first got our trailer that sometimes we would open the pass thru storage doors we would feel cool air but we had sealed every opening we could find including those in the storage areas. Couldn't figure it out.

About two weeks ago my wife pulled the plastic trash can out because something fell behind it and I saw her get the flashlight out and looking around that area. Seems the island has a raised floor under it and she spotted about a 8"X 8" opening under where I had sealed the pipes that dumps into the basement area under the floor. I bought another can of expanding foam and went to work sealing that area off and now we feel no cool air when the storage doors are open. We were loosing cool air through that opening into the area under the floor. So if you have an island with the trash can on one end of the sink pull your trash can and shine a flashlight around the floor under the sink cabinet and see if you find what I did. It was not a big opening but we were loosing cool air out of it.

Rusty

I have extra crown moulding so I could do that but after seeing the pic I think the a larger grill attached to the ceiling is less noticible. I will say it does look like a nice job, just too noticeable for my tastes. Thanks for the pic!
