We looked at the 3410, then found out my Dodge 2500 diesel could handle the 3612 and that's what we ended up with. My unit and at least one other on here had problem with our 2013 roofs, but CR fixed his under warranty and eventually stepped up and fixed mine. Be careful- my roof was not covered by the Xtraride extended warranty. As mentioned above, call CR and find our what coverage they give you before taking the leap. Extended warranty is not a factory warranty, find out what they cover.
There are many nice features in the 2013 and up Elevation models, and I would want some coverage from the factory - especially if it is represented as a factory refurb. Just my $0.02.
