FVTM and Fexcraft were coded by Ferdinand, link to his discord here. He's done a great job with his mods, and is very responsive when contacted about bugs. If you have any issues reguarding his
mods' functionality (not pack visual or config issues), contact him or contact me via DM and I'll reach out to him for you. This being the add-on that it is, here's some information reguarding his mods:

Road Generation
FVTM has an excellent sloped and curved road generator, building slopes with 16 different levels of asphalt. Width is determined by stacking road creation tools (stack of 5 yields a 5 wide road).
Simply click points along a path, and double click on the last point. This will finish the road segment. I've found that it's much more accurate when doing short sections of very curved roads.

Constructor
The constructor and lift is used to modify and paint vehicles in any FVTM addons. To modify a vehicle, right click on the constructor with the vehicle in your hand.
Const. Status- This tab allows you to autoconnect to the nearest lift, which will show the vehicle in said constructor.
Content Info- Name and other information of the vehicle.
Part Cache- If you right click and place a part in the constructor, but do not attach it to the vehicle, you can view it's information here, remove it from the constructor, or install it.
Part Manager- Here you can view the currently installed and default parts, and remove them. Some parts are unremovable, an example would be engines or most cabs.
Part Installer- Fairly self explanatory. Allows you to install parts to a custom category or a defaulted category.
Texture manager- Allows you to switch between various textures. None others are currently implemented in the HTP.
Spraying tool- This is where you are able to set the primary color RGB of some vehicles in FVTM. All the vehicles in this pack are enabled.

Vehicles
Vehicles are part based in FVTM, allowing lots of customization and modification. They also have functions or "programs". These would include lights, or for other packs, animations or tools.
All of the vehicle's programs are available by pressing "k" while in the driver's seat. The default programs are lights, brights, fog lights, blinkers, and hazards. The trucks in the HTP only have
lights, blinkers, and hazards currently implemented. "L" can be used to toggle between no lights, lows, and brights. While in the vehicle menu after pressing "k", use the scrollpad to select a function
and left click to activate. Right click deactivates. For the blinkers, left click is for the left blinker, right is right blinker, and ";" deactivates the blinker function.
By pressing the "R" key, you can access the vehicle inventory and menu. Here you can view any status or information about the vehicle, access the storage inventories, and fuel the vehicle. To fuel
HTP trucks, place a diesel fuel can from the GEP in the box under "fuel". It may take a while, as these trucks hold a very large amount in their tanks. Inventories are split into categories, depending
on the vehicle. The pickup trucks in this mod have a dedicated "bed" inventory. The Chevy 5500 has beds that can be installed, and each adds an inventory. The toolbox and lumber rack each add an
inventory in addition to the bed, under the "bed_accessory" category.


FVTM has a driving system that is much different than most. The "W" and "S" keys increase the throttle and decrease the throttle, respectively. A throttle will remain where it is left at until the
other key is pressed to change it. Turning is much like turning a vehicle- it takes some getting used to. Turning is not immediate, either. To turn on/off the engine, press "ctrl".

Towing and Connectors
To tow a trailer, you'll need to attach a hitch (the gooseneck hitch for HTP) on the "rear_connector" slot. If you right click the constructor with a hitch, this option should come up automatically.
Once the hitch is installed, back the truck up until the hitch and the trailer coupler are within (roughly) the same block. Turn the engine off with "ctrl", and press the number "0" to attempt to
couple to the trailer. If it won't couple, you probably didn't stop the vehicle completely or the hitch isn't close enough to attach to the trailer coupler. To uncouple, come to a stop and press "0"
again.

Okay, so I'm currently working on an update that's fairly large. These changes may not allow you to smoothly transition with your current vehicles, just a warning. The way I originally set up the vehicles with part configs and how the parts were separated wasn't the best way, and one of the big goals of this update is to fix that. Ford, Chevy, and Ram trucks are getting a facelift most likely, and also getting crew/regular cabs plus options for bed lengths. Another thing I'd like to add is two different versions for the Heavy Truck Pack Light Duty Truck Pack, one that's a little more simple and less resource intensive, with just 3 models of trucks plus their respective cabs/beds. The other pack would be wayyyy more in depth, with more models, more bed options, lift kits, aftermarket wheels, and possibly offroad bumpers and offroad lighting. FVTM has some new updates that'll definitely make for some interesting features, like working lights. Now for the name change, might as well explain that. I'm planning on separating packs- LDTP for light duty models (up to 3500/350 trucks), MDTP for medium duty trucks (4500-6500, 450-650), and HDTP for heavy duty models. Not sure when the latter two packs will come out, it could be a while. I'm also currently working on a trailer pack, which will give a redesigned flatbed trailer, horse/cattle trailers for carrying animals, and some other trailers as well. My last idea was a "ranch" pack and "recreation" pack. These would have side by sides, 4 wheelers, specific trailers, and specific trucks. These would be lighter packs that don't add other features some people might not want- i.e. tractors, flatbed trailers, etc. They would focus on their respective category and might even include some block models that relate to the subject. So yeah. Big changes on the way.
