I have been looking into the RV specific GPS's and have got a lot of varying opinions. The question that I have is what logic does the Garmin 760 and RM use to determine routing for your RV? Many report that when using the RV routing it will rout them to truck routs that are longer or keep them off more direct routing. Does anyone know how this logic is set up in the these GPS's? or is it the same logic used for truck routing?

There is NO RV routing available in any GPS. There is trucker routing and car routing. You can add some limitations like weight and length and the manufacturer can add some RV related POI's but the routing will still be done as if you are a commercial truck (truckers GPS) or a big long, heavy car (RV GPS). I suggest that you always check your route online or with a paper map i you plan to leave the Interstate highway system. I really like planning using Google Earth. It not only shows the exact route and allows me to drive it, but you can right click on an active route and you will be able to view all elevation changes along the way in both slope (5%) and elevation gain or loss.

Thanks Bill that was my suspicion after reading some of the threads. How were you able to find this out? To the average RVer if you read their marketing claims they say you can input ht,wt,length and it will find the perfect road for you. I do use Google earth and a road atlas to plan trips and an old Garmin Nuvi. My first Garmin 330 (I think it was) had truck, car, and pedestrian mode. When it got stolen I bought this Nuvi assuming it had the same or more because it was newer and more expensive but only has a car mode. I was trying to determine if the $400 "RV specific gps's" were worth the extra cost.
