Since you are in Texas, or any state with a high heat climate, the important thing is to make sure that not too many of the windows get full western sun. Eastern exposure heats up the house in the am but by keeping blinds down or adding covered deck you can keep sun exposure to a minimum. You really don't want a western exposure since it will be almost impossible to keep temps down in the summer, causing you to run the AC at lower temps.
We have an east/west exposure on our house here in southern California. The east side of the house is all bedrooms and one bathroom which is fine in both summer and winter. The western exposure is the MBR, living room, family room, kitchen, and main entertainment patio. Even though we have trees along that side of the house, the western sun hits the house and patio as it sets which means that we can't use the patio for certain hours because the setting sun beats in on us as it drops under the tree canopy. The sunsets are lovely but in summer it gets too hot. We had to extend the overhang on the west side. This helps on all rooms except the MBR (where we only have a palm tree).
Also remember that the sun sets in the north west in the summer and the south west in the winter so you need to take those directions into account too. Suggest you take some camp chairs out and set them up in the areas where the living room windows will face. Sit in them as the sun sets as well as different times during the day to judge if you should reposition the house. Even a few feet can make a difference one way or another in shade from the existing trees.
So happy you will not be living in the RV much longer. After a while, the charm and excitement starts to fade!
And quarters can get cramped leading to
