Yeah I’m a GC who does mostly remodels and additions. Some new construction too.
Yes we have a 12’ dump trailer that goes with me quite a bit. With all the tools in the truck I can still legally tow 9,000 lbs. The max my trailer can weigh is 10,000 lbs so it’ll be ok.
Those are Zip Walls, they help create a plastic wall separating your work area from the rest of the house. They don’t damage the ceiling, and they don’t fall down if the wind is blowing into the house. As you can tell, we use them a lot. https://www.amazon.com/ZipWall-ZipPole-Spring-Loaded-Barriers-ZP4/dp/B002RL8ODK
