Yes you have to drill in the body.
Does anyone know where I could buy these with overnight shipping?
I have heard that Retrofit Offroad ships very quickly, you'd have to ask them if they could do overnight.
I called retrofit offroad on Thursday and spoke to someone there about expedited shipping, he took my name and number and said he would get back to me with a quote, he never got back to me and I have since left 3 more messages and still no response.
And 3600 miles through the Southwest last month. Again, real nice to have that extra five gallons available!
I did have to weld up a crack in the mount after considerable use. Other than that, the carrier has worked very well, providing enough extra fuel for longer trips through some remote areas.
