[Pirate_Ray]

it's not a mod, its just a .craft file. put it in your saves folder under VAB tab.

i understand, but how do i merge my tank with this rocket without using mods? that is what i ment.

Use Subassembly Manager. http://kerbalspaceprogram.com/subassembly-manager/

That's a mod, which is what he's trying to evade, as he plays KSP vanilla.

@Pirate_Ray - You can merge by editing one of the .craft files to add the adjacent .craft file's parts...But a word of warning: It's difficult, and painful.

Subassembly-manager is another non-invasive (doesn't add any parts and doesn't change any game mechanics) mod you might be better off installing until Squad gets their s* together and implements these must-have essential features into the game's core.

Oh hey, a shortcut for calculating mass w/stock. (I play stock + Subassembly manager)

have the craft as you want it weighed, then take it to the launchpad. Don't lift-off. Instead go back to spaceport, then tracking station. At the bottom of the list is that ship "ready for launch" and if you click on the "i" on the map, it'll show you information about it, such as the number of parts & Mass.

Still no nice way to calculate the mass w/o fuel other than by hand....
