[Which Pragramable GPS ?]

I am looking to buy a "truck" type GPS , which will allow me to punch in the weight and height of the vehicle.

I realize these are a bit more ecxpensive than regular car type GPS units , but I like the idea if I program it for a "truck" and punch in the weight and height it won't take me down any parkways where the camper wouldn't be allowed , or places with low bridge clearances or bridges with light load limits. My Winnie weighs almost 7000 Lbs. !

I would also like a "talking" unit that I can both say the address I am looking for (without having to punch it in) and will give me talking turn by turn directions.

What is a good unit for the money , that will be able to do what I want ?

[Converter Replacement]

I have been reading on here that the old 6300 series converters are "battery cookers".

I have a model 6325 and I want to know if a 7355 will work as a replacement. And if so , can I use either the 7355 R or 7355 RU ?
