You know, Steve,
Your website actually stands out to me, as is, as one of the better ones I have come across. It is very clear and easy to navigate. All of the info is right there, photos are great and finding what you are looking for is intuitive. It does not have fancy graphics to take up RAM and everything loads smoothly.
In a word, your website complements a UL philosophy quite cogently: simple, fine quality, functional, and contains nothing superfluous.
I would say keep it as is and focus on that new shelter you've been working on. :)
