^Good points. And the OP is trying to figure that out it seems.
If he gets bit by the “gotta have _____ because it’s bigger than my brother in laws camper” , then may as well pony up for a diesel now.
If he can talk the wifey out of the 1-1/2 bath Tajmahauler condo on wheels for 2 adults and one miniature person to go to the State park and ride bikes and cook smores on the weekends in the summer, then the options are almost endless.
To the OP, IMO don’t get hung up on a 5ver for casual use. Yes they tow “better” in some respects, but most tag trailers pull fine too and the end result for the casual user is the same. You tow a big trailer down the road to somewhere and then grab a cold beer out of the fridge inside and make dinner and have a few cocktails and go to sleep.
I didn’t realize the vast number of different or unique offerings in the bp toyhauler market until searching the last few months. Within a specific “similar” range, there are probably 100 different models out there all a bit different. And advantages or drawbacks with each depending on the buyers preferences.
Once a person begins looking in detail and comparing different models and brands, the differences become obvious. But starting out it’s sort of a “these pretty much look the same, idk why this one is 30% more expensive....or cheaper.”
