Hi Bev. I don't know anyone, lol
but you could keep an eye on this list.

Here is a link that might be useful: DFW Craigslist

How about renting one, there wouldn't be any mileage to worry about so renting maybe pretty reasonable. bev

You can rent small motor homes, or travel trailers such as you indicate. Check around with some RV sources near you.

Check municipal auto auctions too.

Still looking...Renting is very expnsive and the ones I checked with don't have any left for that week anyways.
I have looked at at least 15 and unless they're only a couple years old they've been awful. I may have stick with a big tent & get a portable a/c unit,buy a new or almost new unit, or squeeze everyone a bit tighter.
I might borrow/rent one from my neighbor. He doesn't think he's using it this year. Actually in almost 4 years owning this lot including the 2 we've lived here, I've never seen him use it! It'll need a good cleaning & thats ok.
I haven't gotten an actual yes from him yet.
