Snowmobile trailer to toy hauler conversion?

I have a new 7.5 X 23 enclosed snowmobile trailer that I bought to transport my atv and side by side. Ive been lurking here for awhile and am interested in turning it into a toy hauler for weekend atv/camping trips. Does anyone know of any snowmobile trailer conversions I can reference? Ive gotten a ton of great ideas from the build logs here but none of them have the front ramp like mine has.
