Maybe just me and BS2000.
Here’s my take. Will preface this by saying up front that I have not yet dropped the GoFast in the back. I did, however, spend a year living out of a rooftop tent on a Jeep all over North America. Had a good idea what I wanted going into this.
Build is lightweight camping for access to fly fishing, rock climbing, trail running, etc. Lots of long distance on highway. Off road for me is a means to another end, not the goal in itself. Stock truck is about adequate for all the off road travel I need to worry about. I don’t shy away from pushing it a bit, enough that I will be adding sliders (going lightweight as I can and still be functional there too). But stock truck does it so far without contact.
Picked the GoFast b/c I just got tired of dealing with rooftops, especially in rainy climates. Too hard to tie flies, cook, generally stay comfortable when the weather really comes in. GoFast was the lightest solution I could find.
Picked airbags for the following reasons. Wanted to stay around stock height for daily driving, rhododendron choked trails to boulder fields, etc. Gas mileage is important to me for many reasons, so 33" tires and suspension are a negative without much positives in my particular case. Recognize need to avoid sag in the back with the weight of the camper, but trips to the scales thus far confirm my bar napkin math - with pax, full gas tank, and equipment I’m just not going to go over GVWR. After adding 300lbs presumed GoFast weight, heaviest load for 5 days still keeps me about 200lbs under, and that heaviest load is just never going to happen in real life.
Went with Firestone RideRite with Daystar cradles. This setup preserves all the articulation I will need in the suspension, and ticks the boxes outlined above.
Figure on reporting again after the final piece (GoFast itself - kind of important) is in place.
Guess I’m surprised there aren’t more operating under similar conditions.
