Stainless is fine.........it won't corrode. Keep in mind that stainless fasteners typically have lower tensile strength than alloy steel fasteners. If you are concerned with fastener strength, you can always go larger, although 99% of the time DIY folks over design with fasteners.
Here is a brief comparison of common fastener material tensile strengths:
316 stainless, very corrosion resistant, relatively low tensile strength (around 70,000 psi or less)
18-8 stainless, less corrosion resistant than 316, cheaper, more sizes available, similar tensile strength as 316 (plenty corrosion resistant for use on the van)
Low carbon alloy screws & bolts around 70,000 psi tensile strength
Medium carbon (Grade 8) screws & bolts around 150,000 psi tensile strength
High carbon alloy steel screws and bolts 170,000 psi tensile strength
