Yes I took mine and I backed in. I also have a Xplorer and have the large window and bed in the rear it was OK but best time I had I rented a moving van and threw a BBQ and ice chest and chairs and a few mattress in the back and took my work crew to see a movie,when we got there we backed in and opened the back sliding door- we pulled the BBQ out and cooked ( no one stopped us ) We all laid on the beds one inside and one outside. The speaker was a problem.
Take a vehicle with an actual "bed" to a drive-in movie? Where's the challenge in that?
Real men take vehicles with buckets seats in the 1970's then wonder why their backs bother them so much when they get older.
