Gladiator Glamping

Hello everyone and thanks in advance for any input! I’m about to sell my wrangler and get a gladiator. My wife wants a camper because of the hardened shelter it provides opposed to tent camping.

I’m looking at SmartCaps as a compromise. The only problem is we’re both 6’2 so we’d need the tailgate down. My question is: if we keep the tailgate down/sleep in the bed with an air mattress how do we enclose the open area where our feet would be? I’m sure there’s something people are doing for this.

She doesn’t want a RTT or any tent version. The point is to have the hardened shelter.

Thanks again for your input/advice!
