I think they could put in a sacrificial anode to reduce rust/corrosion. Helps with protective black magnetite layer preservation on steel. Also something for galvanic corrosion.
Boats have zinc pigs to minimize corrosion and the trailer company could bolt one to the frame.
I buy zinc impregnated paint and do the underneath of steel trailers. Keeps the trailer very happy.
I put grease / old oil / WD40 into pipes or pockets where dirt or ice builds up .... Learned from old cars / tractors with oil leaks / grease build up no rust.
Have 12v fans to blow the air around and circulate heat.
Heater timer.
Various plug ins 120V Plug ins and 12v to charge phone / gopro / portable lights /
Have custom vents and put flexible ducts on the end and run to a sled to thaw out / heat up.
Predrilled holes in the frame to run gas lines.
I decent single or dual propane tank holder .... 5 gallons or 7.5 gallons.
