Pick the Holiday Rambler Nautica 34RX if…

At $414,458 you pay $3,652 more for AquaHot, fireplaces, and Holiday Rambler's quality.

Pick the Newmar Northern Star 3418 if maximum chassis and more slides outweigh AquaHot. The 36,500-lb GVWR with 7,700-lb cargo cap is 4,100 lbs more chassis than the Nautica - meaningful headroom for tow car and gear loads. Four slide-outs deliver more interior expansion at camp, B6.7 360 HP makes 20 more HP than the Nautica's 340 HP, 400Ah documented battery bank handles overnight loads, and four-season construction extends shoulder seasons.
