This is the classic dilemma. Fitting the need for an occasional tow rig into a daily driver. And, the reason for this dilemma is that a dedicated tow rig cannot be justified for two trips per year to the trails. And, there are always the incidental use that a 3/4 ton PU is good for. So, it is a complicated equation.
The simple answer is that you should rent a tow rig and equipment trailer two times per year from U Haul or Home Deport or Sunbelt and not buy a rig. Economically, that plan cannot be beat. Not even close. But, that isn't much fun, is it?
If you can find a place to store a trailer, you can store a dedicated tow rig. I recommend an Isuzu NPR with a 16' landscape bed on it, but there are other choices. These rigs are far more road friendly than an F250 with a trailer behind it. And, if you set a budget of about $12,000 it will last you forever with virtually no maintenance at 1000 miles per year. I think I paid about $400 per year for license and insurance on my Volvo FE. The cost per mile of a diesel 3/4 ton PU as a DD will dwarf the cost of owning a reasonable daily driver and a dedicated tow rig like the Isuzu NPR. Get out the calculator and take a look at it.
This one is 14' and you need 16' but you can get the idea:
