EB50 on SMB website, 7.3 4x4 aluminess $45k
If you donít have a built in stove, SMB adds the microwave as an easy way to satisfy the definition of an RV having a built-in cooking source. We can run our MW for short bursts off the batteries, although I usually run the engine. Admittedly, we donít use it much unless we are plugged in (rare), in which case itís nice to have. We store stuff inside it, like a cabinet.
Are you sure you want/need a sink? We had one and took it and its cabinet out to make space for a third seat, and have never missed it. If you cook outside, how often will you use a sink inside? If itís mainly a water tank you want, then install that and just run a hose and sprayer in a way that it can be easily accessed outside the van. A lot more versatile and takes up less room. Plus no gray tank, etc.
