That's basically my aim. Don't even need that much. I think two tiles worth of storage should be enough. Might just go for a large trike.
Grab a school bus. At the very basics, you can rip out the seats and install trunk space. I was preparing to convert mine, extending it from 5 wide to 6 wide, with a luxurious 2 wide center aisle, storage on either side, an RV cooking unit, and enclosed room, with the wheels protruding further out to either side to allow for an enclosed box. The engine was replaced by an electric and significant storage batteries, as well as being moved back a tile so that the front row of tiles could be armored for those times I just didn't want to spend a grenade to get into somewhere.
And yes, getting an integrated toolset and solar panels makes vehicle handling a LOT easier.
I'd say really, your first goal is to get really good survival (read about it!) so you can harvest shockers. Then prepare a decent bus setup, parked on the edge of town (zombies will try to path through your vehicle and wreck it, so put it beyond their spawn region), and then make forays into the city, particularly to harvest electronics and meat.
Also: why meat spoils in 24 hs? I can't stock it so that I can actually do something else.
Look for Glass Jars - they're usually full of Red Sauce or Pesto or somesuch, best found in houses or rarely as zombie drops. When you find one BE CAREFUL they count as weapons and you will auto-wield them if you're using 'fists' or any martial arts, which breaks them on the first swing! With sufficient cooking skill, you can boil and can the meat - you need water (dirty works), a jar, and meat (rotten works!), as well as a heat source (fire, hotplate, toolset, etc.), and a cooking utensil (pan, pointy stick, toolset, etc.). This creates a 'tool' item, jar of meat, which can be activated to turn into a food container. This means that it NEVER spoils until it's opened, while it still has the same nutrition as freshly cooked meat and occupies 1 volume. Most often I would go slay a critter, eat my fill, and can the rest using bionics (1 charge use of toolset) and have many meat jars left over, combined with a jerrycan of funnel water and a vehicle headlight, then go hunker down and read a tough book!
