Jesse, stick with Sketchup for the moment - I have been using it for modelling and it is quite ok.
I assume you merged your object into a group before exporting as stl file. In Sketchup, select the grouped object, open Window: Entity info: Does it tell you "Group" or "Solid group" up top? If it does not say "Solid", then the object is not watertight- it has a hole somewhere and that confuses the slicer (Cura). There is a nice Sketchup extension "Solid inspector" which shows you the hole so you can close it. Also, Cura will show you any problem area in x-ray view, as mentioned by nallath.
Hope this helps, and good luck with your print.

Because sketchup is very good at making rubbish 3D models. The software is intended to make 3d models that look good, which is can be quite different from a model that needs to be printed.
Have a look at the model in Cura when the x-ray view is active. If there are red area's in that view, the model is broken. If thats the case, the 3D model needs to be fixed.

Just like what nallath said, Sketchup is bad at making printable models. Your best choice is to always check your models if they are printable before printing them. To fix them you can either manually fix them using http://www.meshlab.net/ or use an automatic repair service such as MakePrintable or meshmixer
