I have the 2012 Tracer 3150 and love the outside kitchen as is. The only way to improve it, would be to lengthen the area of the kitchen.
We're a family of 6 and so the bigger cabinets are needed. When I cook on the stove, my coffee maker is just behind it and it works out even though it's tight. A shorter cabinet there would seem to work, but ends up as a big storage sacrifice. I also had seen the extension countertop on other lines and although it could work, it would come with issues down the road as prep areas are heavily used and I don't think such an area could be strong enough long term.
I love the dormer fridge, it's easy, gas powered is over the top in this size range. The sink draining into black is great, as the Grey tank fills to fast anyway. I thought about the stove swinging out, but it gets to close to the outside bathroom door, so again, it's great as is and I like the quick connect gas lines for both the stove and grill.
A skinny second deep drawer would be great for grill utensils. And I think a taller faucet would fit in the existing layout, with the way cabinets are.
Just finished using it all yesterday and we get lots of lookie loos admiring the outside kitchen. I am still impressed with the features Prime Time installed on these trailers and the fact that RV Guy checks into the forum is an amazing testiment of their commitment to the line.
