Travel Trailer

Heartland Prowler 3302TSB

You need a space at least 42′ 11″ long.

At RV Storage Depot that’s a 10×45 space.

Length: 39′ 11″overall
Width: —not published
Height: 11′ 2″as listed

Base height 10′7″. With A/C it’s 11′2″, and we check fit against the taller figure.

To scale: your rig in a 10×45 outdoor valet space.

Outdoor self-park fits most trailers

Most travel trailers and smaller motorhomes do fine in a secured outdoor space. If roof seals and tires matter to you, ask about indoor valet.
