Generator (Little Elm)

Our family of 4 became homeless 3 weeks ago. We tried to stay in our van but the exhaust is messed up and is coming into the van when we run the ac at night. It's way too hot especially for our sons. We are looking for a generator so we can run our portable ac unit in the van. Even if there's a possibility the generator doesn't work we will take it as my husband is handy at fixing things. Thank you.
