Welcome to what I consider the best RV forum on the web!
A few things to consider in your search for the perfect rig for you...
Will you be fulltiming by yourself...or will there be others in the rig with you? That may also dictate the size that you need.
Will you have a toad...and if so..how much does it weigh? (Check the towing capacity of the rigs you are considering)
Is the floorplan a livable option for you? You need to spend a lot of time in it to make sure it "fits" you ...including the bathroom/toilet space.
Where will you need to go for "warranty" work ...and how many places can you go for that type of work?
I would like to suggest you give the rigs a thorough test drive...steep grades are a must.
With all that said..I will tell you that I love our Diplomat with the full wall slide.
Good luck finding the right rig for you ...and please make sure youshare all of your adventures with us here on iRV2!!
