Some 1.13 questions

Hi, I'd like some help with these: [my version is build 7435]
1. How to turn on the additional merchants?
2. Can tripwire be merged to make rolls of tripwire? I tried it with Barry bit it didn't merge and damaged the trip wire. If it can be merged, is skill based? Like MEC or EXP high enough?
3. I've got Bob and Elroy on my team. One of my IMP mercs also has radio operator. While in town (not in combat), I don't get the option to do a radio scan. I'm wearing it like a backpack and it has battery power. What am I missing?
4. Does BR eventually sell trigger groups are are they only found as loot?
5. Got hired Hamous but left the truck in the sector because of hostiles in the road tiles adjacent. I came back less than a day later and the truck is gone. Is it gone for good?
6. Also with Elroy, I'm trying to disguise him as a soldier. I've got him in Drassen and I'm about to send him to Alma (haven't taken it yet). He's wearing a uniform, helmet, pant and carrying some brass knuckles. I don't have the hat symbol so I'm not disguised yet. What are the rules on what to wear to be in spy mode. I read some things about how wearing certain equipment and being too near a dead body will blow my cover.
7. How to drag a body?

Thank you

5 is a bug from original. Truck is probably gone for good, unless you got previous saves. To avoid that in the future, enter truck at least once, so it will register on map screen. After doing this it will never disappear.

If you guys do not mind, i would like to add another question
8. i turned on the zombie mode in order to get some help against enemies in battle for a while.... but now my favourite merc is ill, has some kinda poison ♥♥♥♥... doesn't work taking care through normal cures as long as after getting cured poison goes on again: did you find out where to find any poison cures so far?
