We're using drag radials too .. but really don't want to get stuck in rain with them (knocking wood .. lol) so bringing some street tires ... though we're not dragging a full pit with us (like some of those running hard on the edge of their motors/trans/etc) I would still like carry couple 5g of fuel as well (last year some routes were country forever ... lol .... our buddy had to use his carry fuel couple times .. with 14 gallon fuel cell) .. no room inside for this and certainly not fuel ..
But then there are plenty who have no trailer and were fine as well.
