Both true. I actually won't use GPS while towing. I don't have the more expensive units that can take clearances into account, and I don't trust the in-vehicle system in my truck not to take some weird turn along the route. I write out directions before I hit the road.

On the gas station front, I will also say that I pre-determine those as well. We are 55' bumper to bumper, so not every gas station is a good option for us. When travelling longer distances, I have no interest in pulling on and off highways in hopes of finding one. So, I use Google satellite images to pre-determine my gas stops. I will often do the same for meal stops as well. It's a bit over the top for some, but I don't mind doing it, and it makes for a much smoother trip, for me, when I know exactly where I'm going.

I do this as well with the gas stations, I generally look for a Loves/Pilot/Flying J/TA/Petro station as even their auto sides tend to be big rig friendly. Many Sheetz stations are also an option as are many Racetrack locations. If you have to use a smaller station look for one with pumps parallel to the street rather than perpendicular.

Interstates, US highways and State routes are the way to go. I've never been turned back by a low clearance and I've all over the US. BTW, for peace-of-mind get yourself a Motor Carrier's Atlas at any truck stop. Trucker routes are highlighted and you'll never have a problem.

We have 14 seasons & at least 1800 nights behind us. We make an effort to stay OFF the interstates. We have never had to back away from a bridge with our 12'10" air draft though we have done the middle of the road a few times just to be sure.

The biggest risk is in the CG. We have backed away from a gas station overhang a very few times. Anywhere selling diesel will have a high enough roof if there is not a remote diesel pump somewhere.

Height clearance is simply not an issue to sweat over.

I'm a full-timer for almost 7 years, 46 states, over 65,000 miles.

I NEVER trust any electronic device to make my routes. I do run the route with my GPS the day, or a few days, before I travel. I also take that information into account as I plan my route with software, and print out my route and turn instructions before I start. I also know where I will stop for fuel and food, and look at those stops with Google maps. I'm 62 total feet long from the nose of the 22' long pickup to the end of the back of the rack on the rear of the trailer where we carry a sewer tote.

Like Mickeyfan0805 - that may be too much for some folks.

I also step through the GPS route - Turn by Turn - I haven't seen a GPS that does not allow you to do that. It's a powerful tool, with the ability to cause great damage if you do not know how to use all the features.

While towing I have TWO RV Gps running. A Garmin set on auto re-calc and auto zoom. One reason is that I prefer the traffic information from Garmin. If my planned route in the Garmin shows me going under low bridges, over bridges where I'm over the load limit, etc - I look at each one individually.

The second GPS is a Rand RV GPS. It is set to show ONE MILE ahead, and NO AUTO-RECALC. I want to see the turns and intersections coming up in the next minute. The GPS does show me how many miles to the next turn/ change of highway. If I miss a turn I do not want it telling me to turn immediately. I'll go to a safe place to stop and look at alternatives.

The GPS does not tell me where to go, my route. It advises me. The decision is mine, and there better be a DANGED GOOD reason for me to follow a suggestion from the GPS that conflicts with the planned route.

This might be more than some people want to do.

But I strongly advise everyone, if something seems weird or fishy. Stop. Look. Research. All that will cost you is a little time. Which is vastly cheaper than any likely damage or such.

Last but far from least - my wife understand my system. How to search for information online (it we have a cell signal - which is surprisingly unavailable in places in EVERY state we have traveled/ camped except Rhode Island). She also understand how to program the two GPS units. She is an important part of our travel process.

Also when you have planned a route with 2 inches to spare under a particular bridge BEWARE of fresh paving under the bridge :)

Posted signs are typically a few inches lower than actual clearance so if you bounce a little, you don't hit. Also paving projects include updates to the signs (you will often see where on an overlay project, they gap out the underpass and mill out that area before paving so it doesn't reduce the clearance. Incorrect signs are an extremely rare concern as it will be quickly apparent when local trucks start hitting the bridge.

Can't always go by those numbers posted on warning signs...

The RR bridge around the corner from my office has a posted clearance of 12'2"...

There is at least a dozen big rigs (box trucks X 52') that go under it daily, all have about an inch or two to spare.... You can tell the new guys to the area as the hold everything up and are very couscous , and the regulars don't even slow anymore.

Truckers Atlas, Good Sam Trip planner, Garmin for RV, Googles Map and homework. Been on the road for 11 yrs. doing the byways as much as we can. Only way to see small town USA. Never had to turn around or back up for low clearance.
