So I'm sure some of you might live in a mobile home (as in double wide/single side) so I have a few questions for YOU.

Bit of background on this place. It is 5 bedroom, 3 bath, and I'd say roughly over 2200sqft. Just grazing the max size of a double wide IMO. The place is a little over 10 years old and hasn't been taken care of that great. I'm sure yall remember the problems I had over the winter with all the duct tape specials and I'm still fixing those and other things that where never "fixed". The 4ton AC unit is an 08 Gibson and I just had to replace the fan motor (the outdoor compressor/condenser) to give you an idea of how much these people really didn't care about their stuff.

Anyways I'm having a problem keeping this place cool. The major obvious fact I know that is a problem is on the opposite side of the blower, opposite end of the house (roughly last bedroom, living room area) there is a big hole in the metal ducting. You read that right, METAL ducting due to a freakin dog. Air flow still isn't that bad and the air coming out of the remaining vents is actually cold.

1/8th of the house is blocked off and sealed because it is the master bedroom and bathroom. So basically one end of the house is not accessed so the only door leading to it is duct taped and toweled off to prevent hot air from coming in. The windows are absolutely crap. Single pane, plastic latch, the works. The cheapest stuff you can buy from Lowes it seems.

Here is my idea. The windows we don't plan on using (or will be replaced later, as in 2 will turn into a nice sliding glass door later) and the 2 windows with AC units in them will have solar screen put on the outside, tin foil on the window on the inside, fiberglass insulation following tin foil, then drywall covering the whole works. So from outside to inside it's solar screen, window, tin foil, insulation, drywall, caulking filling in cracks. I hope to use this cheap but hopefully effective setup to not only block sunlight (more so heat from the sun) but also to prevent air from coming inside. The windows are crap, so air does seep in....alot. The only 3 windows I plan on leaving alone are the 2 in the main living room, and the one in the kitchen. The kitchen one is for small daylight entry (to see while pouring drinks without turning on a light) and the living room 2 windows for the Christmas tree in the winter. The AC unit windows will be a bit more of a pain but I think it's doable with a bit of help. Anybody have any ideas or suggestions against this, please let me know. The living room windows have tin foil to block sunlight anyways, but that is easily tore down for Christmas and cheaply replaced for the summer...as is solar screen.

The doors in this place are absolute junk. When I close my front door between 2pm and 9pm I can see sunlight from the western sun. The same can be said for my back door in the morning. It's not that bad, but I know bad seals cause air leaks which means higher electric bill. I don't really care about the back door, so I will probably just seal it off because until the owner cleans up the back porch we wont be going out that way anyways. I just need to figure out an easy and cheap way of fixing my front door sealage problem.

I will also be going around the house trying to fill cracks and gaps with Great Stuff like around pipes and stuff. It works exceptionally well as I've found out over the winter and this brief summer.

Any ideas or words of wisdom that isn't wallet heavy I'm open ears. I went and priced the materials I will need for the windows and I can do this with what I have now (lost my job, remember this). I have a bag of insulation already and it will probably stretch me 3 windows. The rest will have to get insulated at a later date. Before you ask, no we don't want or need our windows to be opened for anything really. Not a big fan of daylight at all and no daylight comes through the windows now as it is. I just see them as a huge energy sapper for the winter and summer.
