We live in Texas City, TX, about 14 miles from Galveston. We just made the trip to Corpus and back using Hwy 35, with exception. The exception for you would be to pick up highway 332 over to Surfside, and then take County Road 257 also known as "The Blue Water Highway." There will be a small $$ toll. I have made that trip with a 1 RWD pulling a Montana 3400RL, and the MH, 40' towing with no problem. The Blue Water Highway is a narrow two lane road but I had no problem keeping it between the lines.
An easy way to get to the Blue Water Highway would be to take 35N to 36S to 288N to 332 to Surfside. There are many other ways to get there looking at the map and none of them are a problem. About 99% of the roads in Texas are good. (IMHO)
Do you have a campground in mind?

It is what it is, and then it is what you make of it.
