Pick the Dutchmen Colorado Travel Trailer 21RDC if…
Pick the Dutchmen Colorado 21RDC if you have a family of four to six and need maximum payload at the entry price. The 2,979-lb cargo capacity is the standout spec at $26,240 - it lets you carry bikes, generator, full fresh water, and a week of food without sweating GVWR. The tandem axle gives more highway stability than the Access's single axle, and the 7,600-lb GVWR-class chassis supports heavy gear loads. Best for families who tow with a half-ton truck and camp at hookup sites.
Pick the Winnebago Access 18RK if…
Pick the Winnebago Access 18RK if you are a couple who wants a lighter tow with a real front-queen-rear-kitchen layout at $1,110 less. The 3,900-lb dry weight tows behind crossovers and small SUVs (5,000-lb-rated vehicles), the rear-kitchen layout puts the most-used appliance at the back for venting and bug control, and the 49-gal fresh tank supports 4-5 days off-grid for two. Best for couples on a midsize SUV who do not need bunkhouse capacity.
