I have had quite a few bassboats but never owned a tandem axle trailer which I am picking up tomorrow (Nitro Z20). My driveway is gravel, narrow where it meets the road, and uphill;it is perpendicular to a 2-way asphalt road. What is the best approach to turning it in while stressing the tires the least? My single axles I just start in the oncoming lane and jackknife them in at a stupid sharp angle but this doesn't seem the best on a tandem as the tires would be digging into the asphalt. Any tips would be appreciated.
