Hi. I also am a retired nurse. I have been retired for 4 years now. I have a 13 ft Burro
that I dearly love. I lived for 5 months last summer volunteering at Sitting Bull Falls in the Lincoln National Forest 50 miles from Carlsbad New Mexico. When I bought the Burro
I traded vehicles and bought a 2015 Nissan Frontier 4 cyl engine with extended cab. I have a very lightweight aluminum camper shell for it. I travel with two small dogs and there is plenty of room for their dog bed behind the passenger seat if someone else is traveling with me. I love the pick up because of all the extra room for chairs, grill first up awning
or whatever. I weighed my Burro
at a local farmers co-op fully packed for the trip west at a local farmers co-op near my home here in Tn. The weight
was 1165 pounds. I averaged 17 to 18 miles per gallon. When I left Carlsbad I picked up a friend at the Roswell airport and we traveled to The Grand Canyon, to Utah, Wyoming, Colorado and back home to Tennessee. I guess that I want to tell you that you won't regret the extra space that a truck has to offer. You might consider a 6 cylinder though.
