Probably a class IV. There are three heavy duty classes ( III, IV, and V) III would work most of the time but unless this trailer is massive a class IV should handle the rough environment.

Review of notes:
 
Since I was getting a little confused about which town was where, I back tracked the forum and found:  
http://www.hondosackett.com/yabb/YaBB.pl?num=1428938728/1622#1622
 
 
Town 1 - 75 miles away: Suspected lab Town, no one goes there. Anyone going there usually ends up disappearing.
 
Town 2 - 200 miles away: Smaller Town like current town; Indian Camps around this town are between 20 and 50 miles away and congregate there for shopping and social events due to its close proximity. It shall be called Indian (Injun) Town. It was a smaller military base abandoned long ago during the Happening and then resettled. It was an Army Barracks Base, meaning soldiers were housed there before deployment so there are many small barracks buildings with a large main street and several side streets but no vehicle hangers or aircraft runways. There are smaller shops and vehicle repair stations. It also has a small communications Tower/center where they connect with the other nearby towns by radio. The Convoy would set up their mobile stores at the far end of the main street. They and the surrounding Indian Settlements are the first towns to sign the treaty.
 
Town 3 - 250 miles away: Fight Town
 
Town 4 - 320 miles away: Lab Town
 
 
Technically, if one goes at 25mhp, one can get to Fight Town in 10 or so hours. At 50mpg, it would be 5 hours. That is if road/highway conditions allow it. I expect the trip to be 8 or more hours.

Note: If this is the case, then Moro will need an insulated cargo box with a refrigeration system on it. Don’t look at the truck itself but at the box, which is insulated and that tiny box on top is the climate control refrigeration unit. It is very small. Too many photo links to post, but look at the link.

It is about 20ft long, 8ft high and 7ft wide; a standard small cargo trailer box. I will assume the wheel bed is already added to it. Like this to give you an idea on its size, though this is on the short side (6ft 6in). Double wheels will give it stability on rough roads:

Then you will need a generator to run this. Something that runs 4500watts (5500 peak) should be fine for this.

(This is a Honda Generator, there are many other brand names like Coleman’s PowerMate (same company that makes lanterns and camping stoves), DuraMax, etc…) They tend to have 12v (the covered round port), 120VAC (the outlets) and 240VAC (the 4 prong outlet) They tend to run around 6 hours on a full tank, about 1 and 1/2 gallons. You can get a larger tank for it for the RPG.
 
Hondo, Ruth and Val have a smaller unit (3000 or so watts), the VW Buses have a 1700watt unit and the dub boxes have 1500watt units. Karl has a 1000watt unit in his camper. Less watts means they run longer on the same amount of fuel when turned on. The generators are used rarely, like when using the washing machine or extended layovers to run the refrigerators and recharge camper batteries. For Fernando, he uses his generator to quick charge the batteries on his camper when needed. They are about the size of a milk crate, if not a bit larger/taller.

“I can help you out. Do you have a guess in the size of the cargo box you will need? You need climate control shipping your wine, you will need a 4500 watt generator with an extended tank to run it when your truck is not running it. Its stock tank will only give you 6 hours of power time. Also, you said you to register your vehicle? You bought or are reclaiming a wreck from the highway?” Jerry says and asks.

Note:
 
I’m assuming you will need both a large cap for the truck and a box trailer to haul. It is better to have both IMO.

“Hmmm... “ Jerry thinks, and then pulls out a folder with some stapled forms, sliding a group of stapled papers to Moro. It asks for the basic information: name, living area, vehicle, where it was found, what was fixed to get it running, other details. “Fill these out and go next door to Tom’s Firearm Shop and ask him to process those papers. It should only take a few minutes if no one has the vehicle registered as stolen. We check for that, just in case.”
 
He pauses and thinks about the truck, “Found On Road Dead… Hmmm… a FORD? Nevermind. You can try Mako’s Mechanic Shop. They deal with various vehicles that would be on a caravan. They do fast work if you are in a rush. They’re just a couple doors down in the next hanger.”

Note:
 
You would need a Camper Truck/Box Truck the size of Hondo’s camper to make it work. I’m just thinking to keep it simple. Because if Maribelle’s stuff was taken and much of it was sold, then there would be more room for others. And the Trailer can be sold at another town when it is no longer needed and still keep the truck. And the box on the truck would be a lot smaller than the trailer.
 
The biggest Pickup based moving truck is 20ft.

But with the double cab that would take away from the cargo box and make it 15ft.

Removing the bed and putting in a box would be a lot of work. It might not be possible by “normal means.” By that I mean, in looking I can only find a Short Bed of a truck is about 6ft and a normal bed is about 8ft.

I can’t find what an extended bed is. I guess it is 10ft; maybe Hondo will correct this figure. Either way it is shorter than 15ft or 20ft. Why? Because it is a pickup truck. There is a thing called a “Chassis Truck” where it is a pickup truck with the removed and the rails exposed. The rails are exposed so you can put something on it. But the rails are set to a standard size and width, which is not on many pickup trucks. This standardization makes it easy to put a cargo box on it. The width and size of the rails on the pickup trucks are not standard. This causes a problem in that a standard third party box would not fit. And the answer left is to tow a cargo box and have a cap on the bed. At least the F350 can tow 15 tons. See: “One-Ton” and “Chassis Truck” on here: http://truckyeah.jalopnik.com/truck-sizes-classification-explained-from-tacomas- to-1613958192
 
A heavy trailer, especially one that is loaded down would bounce as much as the truck. A 20ft insulated trailer, though I did not take weight into consideration is heavy. My concern is the roads, as in tight turns. But if the caravan vehicles can do this, so can Moro's truck with the trailer.

Tom takes the papers and looks them over, telling a shop assistant to see if Moro needed anything else – guns, rifles, bows & arrows, fishing gear as he processed the papers. He leaves the area with and enters an office before coming back minutes later.
 
He looks at Moro to see if she hiding something, her expression, her stance, something that would make a liar out of her. He finds nothing. He then puts the papers on the counter, and pulls out a rubber stamp and rubber stamps the papers and signs them next to the stamp. He then rips out half of the papers from the staple and returns the stapled papers to Moro.
 
“Here you are. Since it is not reported missing or stolen, the truck is yours.” Tom tells her. He then asks, “Need anything for the truck?”
