B Van Owner Learning About Foamies

[kstills]

Greetings.

I own a 1996 Airstream B190 that I've gutted and am in the process of rebuilding, and after literally hundreds of youtube videos I came across someone building cabinets out of XPS foam. Which immediately led me to foamies, which then led me here! I'm hoping I can get some insight into the pros and cons of using the XPS process which might lead me to using it in my build. As a side effort, I've long considered towing a trailer behind the van, so building a foamie utility trailer is not out of the question.

Thanks for a great resource, looking forward to getting your input on all things foam.
