I wish I had you guys 4 years ago, we did the bend thing for a trailer mounted unit & it did soot up the burner. We then put vent through the trailer, used a roof penitration for a stove (same size as the burner out-let)and got ahold of a golf-cart guy to extend the exhaust from the engine (flex tube to muffler under trailer very quite, which we needed). As for the ladders on the top I bet you could weld up a holder on one side which would be away from heat & still hold a lot of ladders. As for heat on the inside we added a vent on the front which could open & close. We did'nt have problems with the engine over heating but we did have other things in the trailer we just did'nt want to heat up. Worked good & still is
