Help my homeless family, safe camping

My family was evicted from our home awhile ago. Both parents were working but they raised the rent and we were just barely making ends meet as it was. We spent some time at tent city, a shelter, stayed with some family but couldn't get back on our feet. Right now we are on a wait list for a shelter but don't qualify for any family shelters right now. And tent city is no longer an option. We are currently living in a tent at a local campground, It is about $40 a night, but keeps raising as summer gets closer. But it is very safe with everything we need for our family for the time being. Bathrooms, laundry, showers, playground, electricity etc. The kids (4 and 5 years old) absolutely love it! But funding to stay here is running out and we have no place to go. I have put up craigslist adds asking to pitch our tent in someone's yard so we could actually afford it, but no luck. I know my family has just hit a rough patch and are destined for greatness, and we had some people donate coolers, food, backpacks, sleeping bags etc. I cannot wait to someday pay it forward. God bless
