The short answer
R-value describes resistance to heat loss through the ground. Use a pad appropriate to expected ground conditions. Check compatibility before stacking pads. Carry the repair method the manufacturer recommends. Treat this as a planning framework, then confirm the rule, forecast, facility, or product instruction that applies to your exact trip.

Essential before optional
Cover shelter, temperature control, water, food, light, communication, hygiene, and a workable exit before adding convenience gear. A borrowed familiar item can be a better first choice than a specialized purchase.
When camping and backpacking differ
Developed campground
You may have a vehicle nearby, established facilities, and easier exits. Verify the site’s actual water, toilet, parking, food-storage, fire, check-in, and accessibility details.
Backpacking
You carry the system and consequences are farther from help. Weight matters, but route conditions, navigation, water, daylight, permits, and turnaround decisions matter more.
Common mistakes
Replace the assumption with a check you can complete before leaving. If it cannot be verified, choose the conservative plan or a simpler trip.
