You can get rid of maggots in a RV toilet by flushing them down. You can also use bleach to kill the maggots.
A vacuum cleaner with a hose attachment and some bug bombs ought to give them the message. There is a reason why they are there in your RV.

Maggots are fly larve if flys are getting under your toilet you should put silcone caulk around the base. if flys cant get under the toilet then they cant lay their eggs. I would lift the toilet kill the maggots replace the wax ring tighten the toilet bolts really tight then caulk
Maggots grow in decaying tissue. They would not be growing on any part of your house. In order to get rid of them, you need to find what has died in the roof and get rid of the body. It is probably a mouse or squirrel. Maggots are the name of the larval form of a fly.
First, find out where they are coming from and get rid of the source. Then, sweep them up and dispose of them. You could flush them down the toilet, rinse them down the sink, throw them outside, etc.
CONSULT A VET IMMEDIATLY THIS IS A SERIOUS PROBLEM. I don't know if this would kill or get rid of the maggots but vetricin is a liquid that you can spray in their eyes and it fights infections and cleanses the eyes.
Throw the rack out and buy and new one!
A toilet is used for getting rid of body waste.
An RV toilet is designed to be mounted over a holding tank. They use almost no water which at first might sound appealing, but unless you have a septic tank under your bathroom it would be bad news for home installation. Unless modified, an RV toilet would not be able to get the solid waste to your home septic system. A home toilet uses the force of the water to move the solid waste to your septic tank. Look for a low flush toilet or a composting toilet instead.
Have the bin man dispose of the material in his refuse truck. Then wash out your bin.
If you have bugs that look like maggots in your microwave, they could be pantry moths or larvae. You can use insecticides like permethrin chemical to get rid of them.
You take that puppy to the vet as soon as possible. Maggots usually live on things that are decaying, so the puppy obviously has either an infected wound or has worms.
