The 57H solves the corridor problem: 16 gallons of holding capacity in a 63 x 10 x 8 inch run, a tank shaped like the space beside a driveshaft or along the outboard side of a frame rail. Ten inches wide and eight tall, it tucks into channels that the boxy tanks in this capacity class cannot approach.
Long and narrow means the roughly 133 lb of full-tank contents spreads across more than five feet of length - easy on any single mounting point, but it does want three or four support points along the run rather than a cradle at each end. The blank itself ships at 19 lb.
Ronco molds a twin, the 58H, also 16 gallons at 63 x 10 x 8 inches - the two differ in their molded-in details, so pull both drawings and compare against your plumbing side. For a longer run still, the 43H stretches 20 gallons to 81 x 11 x 7.75 inches. The whole waste range is in the RV holding tanks category.
