WHAT ONE COSTS
—price not published

The maker never published an MSRP for this floorplan. Unknown is not cheap. Treat any asking price against comparable models, not against zero.

WHAT IT WEIGHS BEHIND YOUR TRUCK
~16,305 lbestimated as towed, for 2 people

dry weight 14,254 lb + fresh water (150 gal, full) 1,251 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.

You want a tow rating around18,120 lb (10% margin)
GVWR (the sticker maximum)17,320 lb
Tongue weight, loaded~3,798 lb (23%)
WHICH TOW VEHICLES IT FITS: 15 OF 95

Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 3715GX's published weights held steady. Fifth wheels also need a pickup bed and are held to the fifth-wheel rating where published.

FINDING ONE

Findable: a few listed nationwide most weeks. Why: Forest River is a volume manufacturer; only one model year. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Sleeping data added by a later pass: Campers Inn page (fetched via the 4015GX URL, which actually renders the dealer's Shockwave GX spec-table widget) lists the 3715GX at Sleeps 8, with a residential king bed and a loft providing the rest of the capacity; full bed-by-bed breakdown for the remaining berths is not itemized in the source. Collected from a census gap: this line had no catalogue record at all. tier, bn and mat are the collecting pass's editorial read, not inherited from siblings. Slide-out count added by a later pass: page text: 'two entries and three slide outs'
