I think both can haul around 3.5k (not sure) but would it create lot of problems if purchasing a camper that is like 2.5k lbs?
I was thinking a luxury car hauling a truck camper is bad idea (considering volvo as well). And think Jeep or something is more suitable to haul something like this
Just the fact BMW has highest maintenance cost , I'm wondering it's bad choice and risk to haul this on the back. If anyone uses there car to haul a camper please chime in.
Just think transmission might get lot of pressure and break down. Using the camper just on weekends (with radius of under 100 miles)
