Purchasing our first TT - is this set up safe?

I tow with the MB GL450 and it has the same capacities. Your biggest issue will be staying within the 600# tongue weight. MB doesnt give you more if you use a weight distr. hitch so you will need an ultra light with a tongue weight near 500#. Models with rear kitchen, rear entertainment have the lowest hitch weights. Also get the Anderson WDH its the lightest and does a great job controling sway. My trailer is a Dutchmen Kodiac 242RESL?
