Has anyone done that ? It would be hard on your back I imagine, but it could be done. Just fold the mower handle down. I predict that there's some guys out there that have done it, but won't admit to it.
The trunks are popular in Jersey.Haven't owned a car with a trunk since '89...
This depends on your area. I have only used a trailer for one job in 5 years. I rented it that day only because I didn't want to dump concrete chunks in the bed of my truck.A trailer is a must in this biz unless you can fab a nice dovetail or something close on a pickup.
