Electrical plug cheater box
Coach is stored at my business (warehouse) and plugged in 7/24 to a 20 amp receptacle. I would like to pre-cool before hitting the road for a day or two. I can reach 2 different (not on same circuit) ...

You have 40 AMPs going to a 30 amp circiut. It will work.
You will never have 40 amps from 2 20's. 20 amps is 20 amps.period.
If the RV is 30 amps (i.e one hot) you are correct. And, you would gain NOTHING. And, if the two 20's were from opposite sides of the building breaker box, you would "let the smoke out"!
If the RV is 50 amps and L1 is 20 and L2 is 20, you WILL have 40 amps available.
Only 20 amps PER LEG. If any combination of appliances pulls more than 20 amps on either leg it will kick the breaker for that leg if utilizing a 20 amp circuit as the OP was inquiring about.
Do it right the first time and install a dedicated outlet for the MH or TT. Have seen too many instances where the proper way would have been cheaper than what was spent on "cheater devices" even before damage to the RV was repaired. It's a wonder some of these people aren't electrocuted with some of the concoctions they can dream up.
