long story short, my brother in law came into a insanely large portable ice fishing house. its 21 feet long by 10 feet tall. it sits on some real dinky wheels and axles. We have a work trip to alaska coming up that was going to require we ship a LOT of gear, which was going to cost us a ton of money, we figured we could convert the ice house into a travel trailer and use it as a base camp when we get to AK (it has four beds in it) as well as a trailer to haul all our gear in. The problem is, I don't know if this thing would be road legal to get us all the way to AK.

is there a site I can go to that lists the regs for a travel trailer/toy hauler? or does anyone know the basics off hand?

thanks for the help!

 

How wide is it??

As far as being legal to tow..
lights
brakes
and of course making it safe and road worthy

 

The DOT (FMCSA ) only regulates commercial vehicles . Your concern is with each state you pull through . As haulin-rv said , you haven't given the most important dimension - the width . Many state roads are limited to 96" . Over 102" wide will require permit . In some states if you have a 102" RV with awnings they require you to have a permit .
Be sure to check for narrow lanes on construction enroute .
