What things upset Paul’s mom about the move to Florida?

From the text, we can deduce that there are a few things that upset Paul's mom about the move to Florida. Here are some of them:
The muck fires.
When lightning strikes on the second day in Florida, the lignite field at the end of the street catches fire. The firefighter tells Paul's mother that the field is always on fire. The muck fire, however, can be further exacerbated by lightning strikes. Since there is no conceivable way to put out the muck fire, the smell of smoke in the air is constant. This is one possible source of irritation for Paul's mother.
The lack of storage space in Florida homes.
Paul's mother laments that Florida homes are as "wide open as cathedrals." Because of the lack of storage space, Paul's mother must store most of the family's belongings at a climate-controlled storage space nearby. Paul also hints that his mother's favorite antiques are in storage; the implication is that the cherished antiques are not a good match for the decor and ambiance of the family's new home. Paul speculates that this is one reason his mother may hate the move to Florida.
The lack of a gym and auditorium at Paul's new school.
When Paul and his mother visit Lake Windsor Middle School, Paul's mother is upset to discover that the seventh and eighth-graders are in portable classrooms. There is no gym or auditorium. When it rains (which is often), the students must forgo P.E. and concentrate on academic parts of their health curriculum. Paul's mother also does not like the appearance of the flimsy-looking portable buildings, and she fears that they provide little protection during afternoon lightning storms.
