Camper hand towing dolly...is it worth it?

I got one on eBay for around 60 bucks for my Shasta Compact. It works great and is a definite back saver. I doubt it would be sturdy enough for anything bigger. I'm sure a heavier dolly would wheel around a larger camper. Seems to me there was a thread about a homemade dolly using an old lawnmower but I can't seem to find the thread.

I have one that I use to move my 1964 Airflyte around the driveway to get it into final storage position (I have a narrow driveway and a lot of trees around). Definitely useful on flat ground, pretty useless with any incline for one person, but it's better than lifting the tongue by hand. I think it's a worthwhile tool to have if you have the space for it. My 2 cents.

We use ours on cement all the time. A trailer can get away from you without help... I like ours, Harbor Freight special at 50 bucks or so.

Grass and gravel, not so good.

The dolly pictured above seems to high for our little trailers. Do some measurements before buying one.

I'd like to resurrect this subject again…
My task with a dolly: to turn my trailer around 180 degrees and then push it about 20 yards more or less in a straight line into its parking spot. The straight line, probably will require a few adjustments and back and forths in order to get the trailer under its new canopy; trailer 7' wide, canopy 9'. I used to do the turn around with the TV, but space was limited and required a lot of coordination with driver and "spotter". Being able to pivot 180 in a tight circle would be nice. Tongue weight on the trailer is possibly 250 to 300. No paving at all, but very compacted dirt, relatively flat. I'm looking at this model: www.amazon.com/gp/product/B00IAM1UEU?psc=1&redirect=true&ref_=ox_sc_act_title_3&smid=ATVPDKIKX0DER
Would love to spend less, but this one has a long handle, wide wheel base and a castor to keep things stable which may be helpful for the non paved surface. Any thoughts? Thanks!

I bought the one from harbor freight over a year ago. It had a variety of reviews, many negative, but the one I got has been fine. My driveway is flat, but I've towed Scotty over onto the lawn no problems, and I'm old and skinny.

I can see the little caster wheel getting hung up very easily on dirt or grass. When using these, it is very easy to balance our little trailers without it.

The bigger the tires, the easier it will roll over uneven surfaces. Mine has flat free tires and I wish they were pneumatic. The flat free tires are a little too soft for my liking. I too roll over grass and dirt.
