Weird mass; tiny rover weighs more than big one

[vincekerbonaut]

Greetings fellow kerbonauts!

So when planning on building a base on Duna, I decided on rovers to transport the different sections around. During the design process of this rover I discovered something weird:

A tiny rover weighs more than a big rover with more parts. Almost twice as much on top of that.

I don't know if this is something weird with KSP or if I'm missing something trivial, but I'm attaching images and .craft files if anyone's interested.

So as you can see, this rover

weighs almost five tons, much more than this one

which only weights slightly under three tons.

The small rover is using heavy struts (strutConnectorHeavy) from a mod instead of the standard ones. If they're from KWRocketry, each strut weights 1 tonne.

Oh damn, so it was something trivial after all. Oddly enough, the heavy struts weights were listed as N/A. But it sure solved my problem! Thank you very much for the quick reply!

You may want to list which mods you use if you want anyone to help.

The small Rover uses a part StrutConnectorHeavy. if that is the heavy strut from KW Rocketry then they weigh 1t each. replace those with normal struts

Alot of the smaller parts do have odd mass though. Those wheels now weigh the same as the mini ones for example
