My son-in-law has a food trailer, and a wooden stand. Depending on the event, he might bring the wooden stand pieces via his pickup truck and then assemble the stand (one he built himself). His family has done events for decades, between him and his brothers they have multiple trailers but it’s not their main gig, just a side thing. Right now, he’s trying to build a restaurant within his building. He and my daughter bought a rundown apartment building for cheap, and are converting it to a combination residence and cafe. Upper floor is the residence. Nice thing is they own it outright, so no lease problems when they get a cafe going. They’ve been doing this on a shoestring budget, with minimal costs and no loans. My daughter, having a university degree, has a good job so income is steady, but will quit when they get the cafe going.
That sounds great. Again, good luck.
