Advice on parking pad size

[Fnp5150]

I have bought into a piece of land near the coast to have a home base for fishing and will be leaving my 5th wheel part-time. It’s a 42’ 5th wheel and I have to make a decision in the next couple of days on a concrete pad size. l’m thinking 14 x40 would be big enough to allow my steps to stay on the concrete ( solid, fold down kind) and a foot or so on the opposite side. No way I can afford a pad big enough for my truck and camper to sit on. Any advice?

1/4 minus, aka crusher fines, is also good for those extended areas and even driveways and RV slabs. Drive over it for compaction, soap it with water and let it dry and it becomes very stable.
I had a 42 x56 pole barn built and i came close to using quarter minus but I knew I would eventually hate myself so I ended up doing 5 inches of 4000 psi concrete, Plus an 8 inch thick section for a future 11,000 pound 2 post hoist. I’m so happy i spent that ~ $11,000. Craig

Well, I had to give an answer to the concrete guy today and I went with a 16 x 40.This should give me enough extra on the sides for my steps and I will likely come in later and frame out a 20 x 20 area on the front and put down a gravel pad for chairs, grilling, fire ring etc. Thanks for all the input guys.

I installed a pad in NC on 1 acre of land I bought for my 40' Carriage Cameo. I have a standard Eaton post that delivers 20/30 and 50 A. The pad is 6" thick and measures 50 by 20 feet. The pad does not have rebar, but fiberglass to give the concrete strength. The base of the bad is 3/4" crushed rock. Cost of the pad in 2018 was $5800.00. I also have a shed with washer/dryer. When you put in water lines be sure to have drains so you can purge the lines when you are away and purge the water in the shed to prevent freezing. If anything else, send me a message, or write it here.

I agree with this… nobody wished for a smaller pad….

That's the truth .
Go at least 16x44. I have a covered 20x45 & allways wishing I had gone 24 wide. It's just money.

Another thought, particularly if you go with a thinner slab, don't assume the wheels are right up on the edge of the pavement. If they are inset a foot or two, it's far less likely to crack the concrete.

I would go no smaller than 16X48. This would assure that the entire trailer is on cement with a little cushion to spare and still leave you with a hard surface when you walk out the door to help keep from tracking in dirt all the time.

24X48

I would try to keep it at least as long as the rig and if you can get concrete under the slide outs that would be nice.

Since it's your place, I assume you will be doing the mowing and much easier not having to mow under the RV.

40x14 = 560 sft
42x16 = 672 sft about 20% more in materials but workmanship cost should be negligible.

How much distance between the rear tires and the back of the trailer? I'm often parked to where only my rear jacks are on the pad. If it's 8 ft you could have a nice 8 x 14 patio. JMT.
