I know you'll get all kinds of recommendations but I'll give you one from my own experience.
We full-timed in a 2007 Itasca Meridian 34H (just under 35' with two slides) for a few years and loved it for the functionality and reliability. We experienced excellent factory support both from Winnebago and Freightliner Custom Chassis Corporation.
This model comes in a 36G and also has two slides. Look for either a Winnebago Journey or an Itasca Meridian. They are essentially identical. In 2008, they changed styles and did away with the 36' model for several years.
Again, some might agree that this is a good model to consider, some will disagree and have other suggestions.

BTW, we are both retired transit bus drivers so are used to bad handling and ride in these breadbox-like vehicles. Yes, our Meridian did not ride or handle that well (as most shorter motorhomes have a problems with) but we were used to driving poor handling vehicles and we were more than satisfied with the way our Winnebago performed in all aspects. The party we sold it to, ended up making a lot of suspension modifications and he later told us that he was very pleased with the ride and handling afterwards.
