But yes the worst thing is trying to go out and pee in the middle of the night.
Pee bottle. I sleep solo, my Falcon Roofnest has pockets that work perfectly. I also have a T4 Gazelle and a cot, but the rtt goes up in seconds. OK - I have to toss up sleeping gear etc but it is all laid out in my 4Runner to be very easy. And the Falcon has a bag for dirty shoes.
I am new to overlanding this year, having retired and I go out a LOT. I have spent over 50 nights out at least, this year. With both options to hand I use the rtt as it is so fast. Also works well in a wind so long as the truck is facing into it. I have got up to turn the truck as it gets noisy and rocks the truck more otherwise.
What bothers me is cooking in the rain, not getting in and out of the rtt. Tomorrow I go pick up an awning with room. I will see how that works.
Also I have my stove in a slide out drawer, so I can cook out the back. I was inspired by Donald with
Softroadingthewest when he had his Subaru. I did the same thing, just a little better with drawer slides. But I think I should pull it out of the vehicle to fry up steaks and bacon and stuff so animals should have no reason to come sniffing around the truck.
I am not so new now, and it is clear every individual is unique in needs and solutions. Which frankly is a royal pain in the arse when you just want a solution. You have to do your own work, make your own mistakes. Also, everything is going to break, eventually, so it is good to have backup plans.
