In summer, the temperature inside a motorhome parked in the sun can exceed 40°C. External insulation mats, usually used in winter, are more effective than internal ones: they reflect sunlight before it hits the glass, preventing the cabin from heating up. Internal mats are less effective because the glass still heats up. Prices for universal mats start at €20–30, for fitted ones from €80 to €200.
