Tight Windy Roads

I would say you are on the best source right here. Go to the correct part of the forum and ask about a particular hwy and you will be amazed at the wealth of knowledge and helpfulness people can have and be.

If there's some risk, I scout it out on Google Maps satellite view. One has to zoom pretty close in, and watch closely where the road really is (which isn't always precisely where Google thinks it is). If you wait until you get to a bend that's too tight it's too late as then your only option is to back out, and that could be rather challenging.

The roads like this I encounter usually aren't "highways" ... They're back country gravel/dirt roads that go to something like a trailhead or canoe launch.

I tow tight winding hills on the back roads of WV regularly towing my 32ft trailer. It’s great way to check how well you have the WD setup especially if it’s raining and wet.

CA has a Bus/MH map with length restrictions.
Check your state.

I drive with a Garmin Dezl 770 semi truck GPS unit. It will route you down truck accessible roads based on your height, length, and weight. It's nice because it gives road warnings of sharp curves, steep grades, bridge heights, etc. I've never been routed down any roads that were too tight, narrow, or clearance issues. There's a car mode for when you're not pulling a trailer. There's an RV specific version that's basically the same unit, but with rv specific sections like campgrounds listings and dump stations.

Be care full where you going if you got a tall FW another problem is the bridges .

You mean like the "Old man drives his trailer into a narrow winding "small cars only" road and gets stuck" FW owner, lol? :) See the whole rescue on youtube here. Entertaining!

Always watch the road signage and if a road starts to look questionable, stop. If you have to back up, use a spotter. A backup camera may or not help. Our Garmin GPS gives us warnings in advance. If you miss a planned turn and think you can simply take the next turn coming up, don't assume it will be okay as an alternative. Checking road conditions in advance on the internet can help a lot. A secondary type road on a map may *look* fine but can be a road from hell when you get on it. Carrying a laptop and having a mobile hotspot/mifi can really help. Know your turning radius and if you have to, take a corner wide even if you have to cross the center line (oncoming traffic permitting). If using a GPS, make dang sure you have the destination correctly programmed into it and don't assume it will always get you there without issues. I always go over paper maps in advance so I have at the min., a basic idea of where we're going and if something isn't clear, I'll take a closer look along with more info.

Checking out how narrow and twisty the roads are is where a mapping program, and/or Google maps shine. You can zoom in to see exactly how the road unwinds. Paper maps simply don't have that kind of detail, although they will give you a rough idea about the road and area.

Hi, and first off welcome to the forum! The general rule is that the driver is responsible for knowing his/her rig and using the roads accordingly. There are loads of signs that you never noticed before that advise no vehicles over a certain length, over a certain weight, over certain height, over a certain # of axles, etc etc. I would say low clearance bridges are more common that curves that are too tight.

Aside from knowing your length, weight and height, I also heed signs that say "no trucks". The sign may not state a reason, but more often than not it's because trucks don't fit.

There are several apps you can use, my Pioneer AVIC nav system allows me to create a vehicle profile where I enter my vehicle size/weight and it keeps me off of roads where I shouldn't be. You can also buy a "trucker's Altas" for old school folks...

Search in the iTune or Play stores for "trucker's maps" or similar.

Also be aware of haz-mat restrictions on flammables...there are tunnels where you shouldn't be with propane tanks (your trailer has 2).

I don't know if it's still available, but Goodsam routing on their site used to show windy, steep roads, bridge heights, etc. I used it on our trip out west in 08, but haven't had a need to route anything complex lately, so not sure if they still offer that.
