What are your opinions on the Pro's and Con's of each. In the next year I would like to switch to 18-20' enclosed trailers. Larger advertisement, beats loading/unloading equipment everyday - plus figure how much you spend in a year in labor for employees to do so, More easy storage such as for tools and carry frequent spare parts, equipment is more protected from theft while at large properties, if someone hits you or you wreck and trailer flips and your mowers are not properly secured, you don't have to face a law suit of a mower going airborne. The main reason I am thinking of switching is because better advertisement, and beats loading unloading everyday. Only downside I can think of is having to fork out the extra $2,000-$3000 for the trailer, and your truck gets less fuel mileage pulling it, and pulling out the mowers at the gas station to fill them up. I think it is worth it, figure you spend AT LEAST $10 or so a day per truck paying your employees to load/unload and hoping they didn't forget to load the spool of trimmer cord. I'm all for enclosed trailers so far..
