Valet makes a big rig easy
A fifth wheel or Class A is a lot to back into a stall every trip. With valet, our team parks it and has it staged when you call ahead. Check roof AC height before choosing indoor. At Norwalk: Grand Design lists the height at 13′ 5″ without a 2nd A/C, so it's at least that tall. That won't clear our 14′ indoor door: we leave 1′ of clearance, so indoor takes rigs up to 13′ tall. Outdoor doesn't fit either: our longest outdoor space here is 45′, and you need 45′ 6″. At Altamonte Springs: Grand Design lists the height at 13′ 5″ without a 2nd A/C, so it's at least that tall. That won't clear our 14′ indoor door: we leave 1′ of clearance, so indoor takes rigs up to 13′ tall. Outdoor is the fit here.

How we sized it
- Length needed: 42′ 6″ (manufacturer’s overall length) + 3′ to back in and close up = 45′ 6″.
- Width: not published by the manufacturer. Width never rules out a space; up to 8′ 6″ fits.
- Indoor: height + 1′ must clear the indoor door listed for the space.
- Grand Design’s listed height is a minimum: it leaves out a 2nd A/C and Grand Design prints no height for one. Over the door it rules indoor out. Under the door it never confirms indoor, so we send you to the office to check.
- Specs: Grand Design published specifications, checked 2026-10-19.
