Do you use a GPS?

[campingcpl]

I was just curious and to get some feed back on people that are using a GPS to trip route when traveling with an rv. I have been considering getting one but was always affraid of it getting me into a tight spot with low clearances or tight turns. I have been doing some research and have found that there are 4 companies that are now making GPS's for RV use. There are a few companies that are making software for laptop's/cell phones/tablets and android devices but not really interested in them. Most of them require you to have mobile internet and personally I can't see spending the money for something I wouldn't use enough.

1. Rand McNally is making one and soon to be coming out with another for RV use (http://www.randmcnally.com/products/rvgps/index.jsp).

2. Magellan makes one (http://www.magellangps.com/Magellan-...FY5Y7AodCG19FA).

3. Tele Type makes one (http://www.teletype.com/c/RV_GPS.html).

4. Garmin makes two that can be used for RV's (https://buy.garmin.com/shop/shop.do?cID=275&pID=93853 & https://buy.garmin.com/shop/shop.do?cID=275&pID=68620)

The prices for these run from a low of $299.99 up to $529.99 (prices can very depending on where you shop). So far (knock on wood) I haven't really ran into any problems other then maybe some tight turns or some small gas stations while traveling with an RV or when I drove over the road. All I ever used was a road atlas. I have missed some exits or have made a wrong turn before because of roads not being clearly marked and was thinking that a GPS might solve some of these issues. If anyone is using any of the above GPS or other GPS units I would love to hear about your experiences with them and what type you are using.
