Sounds like an L45 or L48 would fit the bill perfectly for what you want to do. The dedicated TLB's (tractor/loader/backhoe) have more hydraulic pressure and flow, which of course translates to more lift/dig capacity. They also have stronger/beefier frames and weigh quite a bit more as well.
The only two disadvantages that I see, is you can't take the front end loader off (really not a big deal) and you lose some PTO hp since more engine power goes to the hydraulic pump, vs PTO.
