- Trucks & Sleeper Trucks:
I put RV's in the QoL to help out people with low attention spans in regards to Rising World's building and crafting. Then again, maybe this game isn't for them, and it should be more for serious people like us. I'm being helpful attempting to bridge the gap so I hope the RV's work for those casual folks. What about for us more serious folks? We could have one of those Volvo VNL type long-haul sleeper trucks. That is, IF and when Red51 (or modding) is able to. No rush, no pressure.
(Side-note: I had the video muted missing out on commentary. Feel free to mute the video for my POV.)
Granted, it doesn't have to be American, nor European. It can be a generic Unity store asset, or whatever Red51 can manage at his own pace. A truck is a truck, and it'll help with cargo. Having a sleeper would help for those more remote tasks away from your settlements. Trailer could vary in size, or it could simply stay as a pick-up truck. Again, whatever Red51 plans and desires. Same with modding.
-------
According to Red51 vehicles will be modular, to a degree. Depending on HOW modular, we could potentially implement a normal truck, a sleeper truck (one bunk), or even a Long-haul sleeper truck (as shown in above videos) having a mini kitchen, washroom with shower, a sitting area, and hopefully a bed (bunk).
This would help with remote projects while hauling goods to and from.

Medieval Era?:
Horse-drawn carriages able to seat people, have a table inside, and storage externally. Horses themselves have satchels.
Google up ANY Horse drawn carriage. It comes in all shapes and sizes. Granted, I am also thinking of the enclosed royalty kind where you face one another, though more touristy wagons could also work. If it can be modular, in allowing storage containers to snap on) then that will be enough.
- Royalty kind, though could convert it to living purposes (view wild wild west variants).

Below wagon would do well for Medieval era. (This is more of what I'm looking at).

Then there is the merchant wagon from Spice & Wolf Anime.

Tried getting a full view, something with "less Anime", though this has to do. Even the Anime version of the real-world merchant cart would do genuine wonders in Rising World. I would genuinely start off with this wagon (even if we had RVs & Sleeper trucks prior to wagons) just for the experience. I would place a bed, tons of barrels, and just go to town doing projects in and around my settlements. Oh! And this version only requires ONE horse. Only one. No need to go wild with many horses. 
Or the Unity Store variations:

Bonus:

The above image is simply a bonus for what I was initially pondering about for a Medieval wagon to convert loosely into a living quarters & storage vehicle. Place some small chests into the cart (interior and exterior; Wild Wild West style), and just go to town.
As a Disclaimer side-note:
You'd then use whatever suits your needs, and whatever Red51 is able to work with. Maybe someone will mod these into the game first, especially working around me because you know how people are. Everything is always allegedly my fault so people will mod this for other people while throwing me under the bus every chance they can. I allegedly "antagonize" people, whatever that means. They fail to realize Rising World is hurting. It needs every bit of help and support it can. People need to stop labeling me stupid crap and realize Rising World is hurting. It needs help.
Now, that's the last bit of feedback I have. I forgot to post the long-haul sleeper truck suggestion in hopes it'll help people out. I was considering adding it to QoL thread, yet placed it here. RV suits the QoL better, even if Long haul sleepers would help with construction. I'm all out of ideas so for those who oddly hate me I'll be silent again for awhile. Maybe until Red51 notes when the game updates.
