Slide-in camper in a Ranger?
I have had slide in campers in 3/4 and 1 ton pickups and pushed the weight limits on both. The 1 ton (Dual RW) was the most practicle and safest (IMO) - it was almost 7600LBS fully loaded!
I like my Ranger, but I don't want to see how it would perform in a good cross wind with a slide in camper.....
I also agree with Ranger Pat - you will most likely be overweight after you get all you stuff in the camper.
Be safe and be careful!
Just my two cents .....
