They are round not the traditional square type.
We too live in central Texas and we too have the two sky domes. We are brand new to RVing and we went whole hog in head over heals. Bought a Phoenix 33ck and have only driven it home to the newly laid pad. We then rented out the house and have been living in it full time since early July this year.
First off we thought our single AC unit was completely shot. Then we discovered how much heat was put off by the sky domes. We immediately conspired ways to stop the light/heat.
Our final solution was to go to a hardware store and purchase an 8x12 sheet of 2in aluminum coated foam sheeting called R-Max. This stuff has a high "R" rating and is relatively expensive if you were going to use in your entire house ($20+ per sheet). The material on one side has vendor printing all over it, but the other side is shiny aluminum/silver color. So we cut it to fit the sky domes and then taped the edges with clear tape. We originally had added velcro tape but found that this stuff is so light that it just needed to slide past the velcro backing which held it in without issue.
Two nice things:
1- The one in the shower has no cloth material on it so water splashing on it isn't a problem (the edges we taped).
2- The reflective material looks fairly decent with the LEDs and reflects the light into the room very nicely.
And of course it solved a huge heat problem in the RV but we also added sheets of thin bubble core radiant barrier in the windows with blinds pulled down and we only run the indoor LED lights during the day to reduce heat.
Now to my final question: We are still running at the most 15 degrees different than the outdoor temperature. (up from 5-7 degrees before blocking the sky domes!) Is this difference normal for one 15k btu unit? Of course the dealer told us it "should be fine", and the salesman said "I only have a 13.5k in my unit". Over all, we cannot keep the until below 85+ during the day when the trees are not shading the unit. As soon as the trees shade the unit, the temp drops from the mid to upper 80s down to the 70s fairly quickly. At night it drops us into the mid 60's.
Most of what I'm hearing is that we need a second A/C unit. However this RV has pretty good insulation with radiant barrier, etc. So I'm not sure there isn't a problem with the A/C unit.
Outside of adding a RV/Car port (on the list eventually), we can't think of much else to do.
