To haul two rigs, I'd be looking at goose neck trailers. Two full size rigs + a suitable trailer is at the upper limit (and probably above) of what I'd tow with an F250. For that kind of load, I'd want at least an F350 in front. I've seen it done with an F250 but I wouldn't feel comfortable towing that load.
Keep in mind that free advice can frequently be worth less than you pay for it.
