Hi everyone. I'm just hoping to get any ideas for a mobile bathroom. I don't know about you, but I drink close to 2 gallons of water daily which means I have to "water the lawn" ALOT! Lol. I've nearly been caught by a customer several times over the years, but they were luckily all just near misses. That changed the other day and I was throughly embarrassed! Luckily the customer laughed it off. Anyhow, I'm wondering if anyone out here has solved this problem? I have an open trailer, so I can't just stick an RV style toilet up there and hope for the best. Lol. I either need to build a little structure for it, or have some kind of pop up structure and keep it in the bed of my truck. The bed of the truck is actually preferable as I really can't afford to give up a 4'x4' area of my trailer. But I also don't want a 7' tall box standing in the bed of my truck. Lol. All the pop up structures I've found are cheap tent material that won't hold up and will also be a hassle. I've thought of building a flip down box so it's not so tall except for when you need it, but can't really think of a good solution for the door. Any ideas??
