Yes your dads 1500 will do it.
No it's not worth it.
You've asked for opinions and gotten the whole spectrum so there's not a lot of what do y'all think room left. If you haven't already contacted Stan or river runner then you haven't really explored the other options provided. While i am all for adventures and have done some questionable stunts in the name of land cruisers shipping looks more reasonable for your situation.
While fj40z used a 1500 v6 dodge to haul a 40 back from MI without issue other than a rediculously steep driveway at sellers the risk to reward factor is mute. Plus his probably weighed less with all the rust lol. However the ticket risk Ramon noted and the inexperience of trailering point to shipping.
I understand the situation too, Been there. I picked mine up from Canada but drove 12 hrs to meet the buyer over a long thanksgiving break in NY to inspect and secure and we used Uship.com to secure a reasonable price to ship to nc. Heck I even got him to split it with me.
$416 bux Niagra ny to Greensboro nc.
Can't beat that. Gas alone would have been close to that and is be driving i95 in a 33 yr old unknown vehicle. No thanks..... But I did consider it

Granted you have to add the cost of the first trip should you chose to make it but if so make that the adventure.
