Do you have airflow coming from the vents? Is it cool air? I've seen a lot of flex ducts fall off the registers or boots and blow the air in dead space. If the air is there but not cool that would indicate a problem with the ac unit itself. Compressor not starting or low refrig charge....

There is cold air blowing thru the vents. Seems like the windows r putting off more heat then ac can keep up with. 100į outside and 78į in trailer. Won't get colder. Think I gotta do something to windows.

Yeah sounds like capacity issue on the ac. One ac or two? How big is the rig? Most people opt for two acs if avail on the bigger rigs. Over 34 ft or so. When your baking in the sun the one won't keep up. My windows are tinted pretty deep but I still feel the sun heat coming thru. Mfg will tell you that there designed to only do 20 degree diff than outside ambient air. Example- If it's 95 outside then the ac can only do 75 inside.

If it's 100 outside and 78 inside I'd say you're doing pretty good.

Take a temp reading at the return vent and another at the discharge vent. There should be at least a 10 degree drop from the AC unit.

Dual pane would help a lot but a little late for that. Not even sure if that is an option but it was on my crusader. I have had some success with the smoked max air vents and you have to cover that skylight in the bathroom if you have one. That damn thing pours in the heat.

Fit windows with reflective bubble insulation. Works wonders. I can't explain very well what we did with the AC fan discharge, but think of it like a tent shaped piece that direct air flow more efficiently to the ducts. Increased the air flow a bit. Also insulated return air box inside and out like some have done on here. Used the same reflective bubble insulation and used spray adhesive to attach.
