Ehm, no offence, but are you sure that you have made the model your self? I can see that you have googled a converter for google stetchup to zmodeller AND that you have searched for a firetruck at google sketchup. Just make sure that ppl don't get the impression that YOU have made models you show by your self, if you actually have downloaded them - IF you have downloaded them it is very important that you give credit to the person who have made them, but first of all you will have to ask for premission to use them - Not saying that you have "stolen" the model, maybe you have just looked for some inspiration, but be carefull about NOT STEALING OTHER PERSONS MODELS.
