GM 8.1L is a fantastic tow beast. It just gets poor fuel economy unloaded. If this is a dedicated TRV, that may be a good option. Otherwise, GM's 6.0L is underrated. GM has used it since 1999 I believe, making small changes over the last 15 years. It gets decent fuel economy towing and not, better than my 2003 F-150 (2V 5.4L). If you can get into a 2007.5+ 6.0L 6-spd trans, you will love it.
Diesels over the last 10-15 years also make great power. But they have limitations too. They do cost quite a bit more used and new.
Curious, what are the Diesel's "limitations" ?
