I have pulled three different 5ers with my 05’ f-250 6.0. My latest is the 2022 295. Not the weight of yours but the power and payload of your 350 would be plenty. And as far as your miles go, once it’s bullet-proofed it is bullet proof, don’t listen to anyone who tells you otherwise. Cheaper to fix it once than buy new. If yours is already, then your money ahead!
