Im going to use for sand and wood/field trails, and occasionaly tow it to the mountains in colorado. I currently live in nebraska since laws are kindy leniant here i plan on making it street legal, I only live 1/2 mile from work and there is are river trails between there, lots of sand and wooded areas. I want it to be a four seater with a cargo area for the dog, camping equipment etc. As for tires I plan to due a 6 lug conversion and put 235/75r15 on it before i make the buggy so final tire size will depend on how well it runs on those. The car is a station wagon but that means if i bought the plans from rhinobuggies then I would have to get the humbug plans which i think is freaking ugly. Another question that i have is if it is possible to remove the body and have a frame for measuring off of im pretty sure that is not as i beleive that it is a unibody. Thanks for the input.
