Garmin RV770 question

May 10, 2019, 12:39:19 pm

I'm generally happy with the Garmin Rv770 gps. However, one thing bugs me. It tries to route me around roads with TRUCK weight limits lower than my coach weight. Is there a fix?

I see the same thing happening and will see if someone else posts a setting change. Here in Los Angeles the signs use the wording commercial vehicle weight limit and I ignore them.

My 770 consistently tries to prevent me from driving over bridges with weight limits below my coach weight, even over culverts that have a weight limit posted.

I assumed that weight rating was what the bridge was engineered for(I'm sure a very conservative rating) and that a 40,000 RV weighs just as much as a 40,000 commercial truck.

Tom can you tell the Garmin your coach weighs less?

Yes, I can tell the Garmin it weighs less, boy I want to avoid real over-limit conditions, like bridges. Not cities trying to reduce heavy truck traffic.
