My Toyota
 We have a Travel Trailer - about 6,800LBS and do some serious hills Santa Cruz Mountians and such.  The ride is very nice - lots of power on demand.  I have to say my Jayco G2 - if not for my rear view its like its not behind me.  The NAV and Radio are a little bit of a reach.  The seats could use more of a wrap around lumbar support.  Other then that - I really love the truck.  I have every option you can get!
