road restrictions

I have a class a motorhome and am pulling a car on a dolly. We are going out west, how do I find out about any road restrictions for a vehicle of my weight and size before I go? I bought a good sam gps, says there are road restrictions on my route but doesn't tell me what and where. Also, I understand there are some tunnels with propane restrictions, I am very confused about all this and don't want to waste time and gas going the wrong route. Maybe there are so few restrictions that I shouldn't worry about it...could really use some veteran advice. thanks

Road restrictions come in all sizes. As far as height limitations, check out this website: Low Clearances Maintained by AITA, it lists by state all roads with any overhead clearances less than 13' or 13'6", depending on the state.

Weight limits are unlikely to be a common problem, unless you're a very large and heavy coach trying to go down a very small road. In any event, unusual weight limits are almost always posted by signage along the road.

Where the truck or motorhome oriented GPS unit should be very useful is in helping a vehicle of your size avoid dead-ends, sharp turns, or tunnels that would be problematic. We have a Rand McNally we bought last year and have found it to be unreliable in that area.

A simple planning tool that I use (in advance) is to go to Google maps in the sat photo mode and scan the road I want to take. If I see any large trucks, I know the motorhome will be fine.

Very few restrictions in the west. I've never found a tunnel restriction although I suppose there are some. Right now there's a restriction on one bridge, The Bridge of The Gods in the Columbia gorge. It's something like 8 tons and the bride is narrow and a toll bridge so I avoid it anyway.
CA has restrictions on MH's over 40' on some roads but I've never had a problem there either.

There are some low clearance tunnels in southwestern South Dakota. Off the main roads; so, should not be a problem.

Get the "Trucker's Atlas". If the route is marked as a truck route, you're good to go.
