I have a fiver with 50amp service and only one AC. We are planning a trip staying at state parks with only 30 amp available. Will we have problems using a adapter?

You should not have a problem unless you try to draw more than 30 amps.

No. I have a 30amp MH and can run both ACs....not much left of course. Sill run 1 AC, Microwave and other small amp stuff.

Camped in a 5ver for many years. It had the 50amp service and we used a 30amp adapter all the time. Only things you couldn't run together were the A/C and the microwave or a blow dryer with any of the others. Just be cautious on what electric components you use. The main drains are electric water heater, blow dryer, A/C, microwave. One at a time on those and you'll be fine. Ours actually had two A/C's but we couldn't run them both on 30amps.

No worries! The breaker you would most certainly pop is on the pedestal so check there first. Only one A/C at a time and we turn off the A/C when using the Coffee Maker and or Microwave. We don't use the hair dryer much but at 1500 Watts it's a hog and would pop the breaker with most anything else on. 1000 Watts is about 9 amps so you can apply that rule to your other appliances to know when your approaching 30 AMPS. If you do go over you won't hurt the coach, just remember to turn off the appliances before you reset the breaker in the pedestal.

The RULE for 30 amp is normally TWO big ticket items. though they do make air conditioners that are '2 big ticket" items (basement air units are often this way) if yours is a roof air It will be a "1 ticket" ride.

Big ticket items
Air Conditioner
Water Heater
Microwave
Converter.. IF it is big enough and the batteries are dead.
Space heaters.
Electrice "Burners" (used for cooking, like an electric range but only one (or 2) elements)

And that's about it.

Our previous motorhome had the same setup but with 2 ac units. Never a problem but ours had a energy management system that would shed loads when demand was greater than 30amp then turn them back on when the loads decreased.

Have you read your owner’s manual for information on using 30 AMP power for your coach?
In my manual it states that it is OK to run the entire coach off of a 30 AMP power pedestal with an adapter. The only reason my camper came with a 50 AMP power cord and breaker panel is because the unit is pre-wired for a second AC unit. This is when the 50 AMPS are required to run two AC units at the same time.
If you are worried and still want a 50 amp power for your coach buy a dual pig tail adapter from Camping World, or your dealer. See attached link. Worldwide Merchandise Company - 50-Amp RV Box Adapter - D11-136 - Electrical Adapters - Camping World

I agree with Jim..

We just got a fiver with 50A service, but only one A/C. Our last fiver was 30A, so that's what we have at home. Before the new fiver got here, I bought a Marinco 30-50 adapter. Here's what it looks like:

I used a 30A extension cord and plugged the adapter into it. Works like a charm!

I even took and old 30 amp extenstion that had a bad end, cut it off and wired on a round 50 amp rcpt to mate up to the rig, so I have a 30 to 50 cord that I use when only 30 is avail. Just don't try to run the AC, Microwave, and Water Heater on elect. You will be fine with the AC and Micro, but if that WH kicks on most likely things will go dark except for the 12V lites.

Have been running two 13.5 Penguin heat pumps on 30 amps for years with no trouble. However if the campsite voltage goes low they will draw more amps so they may blow a breaker. A voltage booster would be of benefit in that instance.
