I will add that "DIY" tubeless has worked very well for my Fargo, allowing me to use very, very light (360 gram!) Furious Freds in goathead country. The rims, SnoCat SLs, have quarter-sized holes around the perimeter for lightening, and tires tend to fit loosely on them. Stevie's built up the rim bed with Gorilla tape and split tube (thus adding back some of the weight of the inner tube) and applied Stan's (must try Orange Peel). The tires hold air very well for weeks and I've never "burped" a bead.
An earlier attempt to use Stan's in inner tubes was a dismal failure, I suspect because the lower pressures -- 20-25 psi -- were not enough to force the sealant into the punctures. Note that I've had the tubless F Freds at pressures from ~15 to ~35 with no problems. Note too that I have to add 2 oz more sealant at approximately 3 month intervals to replace the stuff that has dried out in our very dry climate.
