Only using 110v in a 240v panel
I am building a food trailer and I have a 240v subpanel but I only have 30A or 50A service outlets at most places I want to park. Is it safe and/or up to code to jumper across both bars and feed both bars the same single phase 110V and only use single pole breakers. I don't have any need for 220V.

Nominal voltage is 120v not 110v.
Basically yes but the lugs are only rated for one wire. A good way to do this would be install a 50 amp two pole breaker and jumper between the two poles. Your 120 would go to either lug of the panel.
However I see a red flag in your plan. You mention a 50 amp connection. Most 50 amp RV connections are 240 volts. It is probably better to use only one side of the panel for breakers. Then you could make an adapter to convert a 50 amp 240v plug to 120v 30 amp.
