Need to buy a NEW entry level RV - Any suggestions ?

Choose whichever on works the best for you. Rental companies buy exactly those listed models by the hundreds, they will stand up to "it's not mine, I don't care" abuse.

You are probably looking at 2014 model year now. In your price negotiations, be aware that you will own last year's model, used, nominally a year old, the moment you drive it off the lot.
