Thanks, folks. We're 58' with a 38' motorhome, dolly and car. We're 12'6" so I use 13.0'. The weight is essentially 26,000 with the car and ready to hit the road.
The Garmin RV 785 routing to our home is "peculiar" whereas the car Garmin does it fine. The route from the interstate is literally is two right-hand turns on to our street.
The RV 785 tries to take us too far north three miles early and down a 10' wide 2-lane street, and then a left and then a left and then a bunch of side streets.
When I set a custom avoidance for the northbound streets, it takes us correctly down the 4-lane state route that the interstate exits on to, but goes
past the street that leads to our street, to the next intersection a mile away and then brings us east through a bunch of side streets. If I fix that with a custom avoidance, only then does it turn right on to the street that leads to ours. It's like it thinks something is wrong with that road or something. It's 10' wide and only 0.8 miles distance to our street and pretty nice, actually.
The radius feature looks like it will do the trick.
Time to break out the old credit card, methinks.
